Since June 2021, Alfa Chemistry Materials has been optimizing its supply of MOFs and COFs compounds and today the company announces to have completed the upgrading work. Now a large variety of MOFs and COFs products are readily available for customers worldwide. MOFs are three-dimensional materials made up of secondary building blocks composed of metal ions/clusters and organic ligands whereas COFs are 2D or 3D highly porous organic solids made up by light elements such as boron or nitrogen. MOF compounds have a very high surface area, which makes them of much interest for catalysis, or for storage or adsorption of other molecules in the pores. “According to statistics in the Cambridge Structural Database (CSD), the number of MOF structures being published are much larger than the number of COF structures,” says the Marketing Chief from Alfa Chemistry Materials. “Due to advantages like high surface area, easy functional modification, and versatile structural designability, both MO...

Quantum dot nanotechnology has successfully entered numerous electronic and biomedical industries. On September 8, 2021, Alfa Chemistry announces to provide CdSe/ZnS quantum dots , one of the various subtypes of quantum dots, for customers across the globe. Owing to their unique properties such as superior photostability, high extinction coefficient and brightness, and large Stokes shift, quantum dots have become very appealing for industries that produce electronics like solar cells, transistors, LEDs, medical imaging, and quantum computing. “For researchers who are looking for good quality CdSe/ZnS quantum dots, currently we have CdSe ZnS core shell quantum dots and CdSeTe ZnS quantum dots for their choice,” says the Marketing Chief of Alfa Chemistry. “And as time goes by, we’ll keep adding more to this category.” CdSe ZnS Core Shell Quantum Dots With a purity of 99+%, the CdSe ZnS (short for cadmium selenide zinc sulfide) core shell quantum dots has wonderful optical propert...

Earlier this month, Alfa Chemistry Testing Lab announces that the company starts to provide perfume testing services for organizations, academic institutions and government agencies who are seeking for contract laboratories to complete analysis and testing for a wide range of perfume-, fragrance- or aromatics-related items, no matter they are finished products or in-process materials or simply raw materials. Perfumes can cause health risks such as skin diseases, nervous system problems, and can reduce indoor air quality or even cause allergic reactions among some people exposed to the scent. These adverse effects may be caused by the fact that the perfume is not produced in strict accordance with industry standards, which proves the necessity of analytical testing for perfume product to ensure its quality and safety. “The testing of perfumes, aromatics, and fragrances is a process that examines the physical and chemical structure of a product. This process is an indispensable ste...

To meet the increasing market demand for pollutant analytical standards and certified reference materials , Alfa Chemistry recently announced to offer a wide range of organic pollutant standards that may be used in the analytical testing of environment pollutants. Organic pollutants include phenols, chlorinated phenols, endocrine disrupting chemicals, azo dyes, polyaromatic hydrocarbons, polychlorinated biphenyls, pesticides, etc. Over the last few decades, increasing numbers of water-soluble organic pollutants have been found in the environment. Environmental pollutants are of serious ecotoxicological and health concern worldwide. The newly added product line of organic pollutant standards at Alfa Chemistry covers: air pollutants, aldehydes / DNPH standards, PCBs & dioxins standards, perfluoro compounds, phenol standards, plasticizers & phthalates, polycyclic aromatic hydrocarbon (PAH) standards, volatile & semivolatile standards. Air Pollutants, Aldehydes / DNPH S...

As a professional third-party testing organization trusted by customers worldwide, T,C&A Lab, a branch of Alfa Chemistry, recently announces to start to provide rock testing services in compliance with ISO, ASTM standards and industry requirements to ensure the selected materials meet the project requirements. In many projects such as hydrocarbon and energy project planning, accurate characterization and more detailed formation properties of rocks are needed for decision-making. “Rock testing is a general term for the determination of all kinds of basic characteristics of rock. The specific test content should be determined according to the type and scale of the project, as well as the engineering geological problems to be solved. Rock testing measures are usually performed at high load on intact samples, sometimes at high temperature,” says one of the senior scientists from Alfa Chemistry. “With a long history of technical success, Alfa Chemistry is committed to creating the sa...

Actively involved with environmental protection, Alfa Chemistry have been providing a wide range of environmental goods standards for scientists and researchers. Earlier this month, the company announces to enrich its supply by adding chlorinated phenol and resin acid standards , which can be used in the analysis of pulp and paper products and effluents. Residues of chlorophenols have been found worldwide in soil, water and air samples, in food products, and even in human and animal tissues and body fluids. These chlorinated phenol compounds may act as promoters or cocarcinogens as the immune system is particularly sensitive to their toxic effects. Resin acids are organic wood extractives, which significantly contributes to an increase in the toxicity level of pulp and paper industry effluents. And once entering open ecosystems, resin acids will accumulate and exert toxic effects on living organisms, which ultimately leads to the ecological imbalance. In the past decades, researche...

Earlier this month, the management of Alfa Chemistry Catalysts announces to have released a new catalyst product line of phenanthroline ligands , which have found potential applications in a broad range of fields such as optical materials, organic chemistry and biomedicine. Phenanthroline is a heterocyclic organic compound and has a planar rigid structure and plays an important role in coordination chemistry. A phenanthroline ligand refers to a ligand having a phenanthroline ring in its molecular structure. “1,10-Phenanthroline is a classic ligand in coordination chemistry, which couples versatility in metal ion binding with peculiar properties of its complexes. Meanwhile, phenanthroline has increasingly become a versatile ligand for advanced functional polymeric materials,” says a spokesperson from Alfa Chemistry Catalysts. “To date, phenanthroline ligands have been broadly applied in three fields, namely, optical materials, organic chemistry and biomedicine.” Phenanthroline Lig...

Knowing what customers truly need, Alfa Chemistry, a trust-worthy chemical supplier, announces that it newly releases a portfolio of protection reagents for researchers worldwide, which will help solve one of the biggest difficulties in the multi-step synthesis of natural products. In organic synthesis, several sites or functional groups in a molecule may react with the reactants, but only specific sites are needed for the reaction process. Thus, chemoselectivity in functional group transformations is always a critical issue that needs to be tackled. “Efficient protection should meet several criteria. First, they should selectively and easily react with protected groups to achieve high conversion rates. Second, they should be stable throughout the whole synthesis process. Moreover, the protecting group in the protection reagents should be easily removed when not needed or when the functional group requires manipulation,” says the Marketing Chief of Alfa Chemistry. The following ...

3D printing materials are regarded as one of the core foundations of the development of the 3D printing industry. At present, the most popular 3D printing materials are: engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materials. In addition, food materials such as colored plaster materials, artificial bone meal, cellular biological materials, and sugar are also available in the field of 3D printing. Ceramic material Ceramic materials have high strength, high hardness, high temperature resistance, low density, good chemical stability, corrosion resistance and other excellent characteristics, and therefore have a wide range of applications in aerospace, automotive, biological and other industries. The ceramic powder used for 3D printing is a mixture of ceramic powder and a certain kind of binder powder. Due to the low melting point of the binder powder, laser sintering only melts the binder powder to bond the ceramic powder together. After...
