CAS :<p>2,4-Dihydroxycinnamic acid (2,4-DHCA) is a naturally occurring compound that is synthesized by the shikimate pathway. 2,4-DHCA has been shown to inhibit the growth of influenza virus in cell culture. 2,4-DHCA may provide protection from influenza in humans and animals by inhibiting the release of inflammatory cytokines such as tumor necrosis factor and interleukin-1 from cells. This anti-inflammatory effect has been observed in animal models for various inflammatory diseases including arthritis and asthma.</p>Formule :C9H8O4Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :180.16 g/molNaphthyl glycidylether
CAS :<p>Naphthyl glycidylether is a chemical compound with chemical stability, which makes it useful for the manufacture of ethers and epoxides. It has been used as an acid catalyst and in the synthesis of polycarboxylic acids. Naphthyl glycidylether is also used to produce genotoxic impurities that are not removed by sterilants or metal hydroxides. This substance can be found as an impurity in some disinfectants, such as mercuric chloride, which can cause toxicity when ingested. In order to determine if naphthyl glycidylether is present in a material, a plate test can be performed to detect its presence.</p>Formule :C13H12O2Degré de pureté :(%) Min. 95%Couleur et forme :Colorless Clear LiquidMasse moléculaire :200.23 g/mol3-Nitrophenol
CAS :<p>3-Nitrophenol is an organic compound that is used in wastewater treatment, specifically to remove nitrogenous compounds from the water. It reacts with a hydroxyl group and a nitro group to form a molecule with three nitro groups. The presence of this molecule in wastewater can lead to population growth, which may be reduced by thermal expansion. 3-Nitrophenol is also used as an electrode for gravimetric analysis of metals and as a reagent for the detection of sodium ions. This compound has been shown to have a ph optimum of 7.5, but will react with hydrogen bonds at any ph value.</p>Formule :C6H5NO3Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :139.11 g/mol
