Mercuric Chloride AR (Analytical Reagent grade) 100g is primarily used as a chemical reagent for organic synthesis reactions, acting as a catalyst for specific chemical transformations, including cyclization reactions and addition reactions between aromatic amines and terminal acetylenes; however, due to its high toxicity, its use is carefully controlled and often substituted with safer alternatives when possible.
Nipastat : used as a preservative in pharmaceuticals, cosmetics, and food.Is a white powder at room temperature, but it typically dissolved into a liquid product. Also acts to prevent the growth of bacteria, mold, and yeast.
Benzenesulfonyl chloride is prepared by reaction of benzene and chlorosulfonic acid or from the sodium salt of benzenesulfonic acid and PCl5 or POCl3. It reacts with Grignard reagent from N-unsubstituted indoles to form oxindoles or substituted indoles. Benzenesulfonyl chloride is the derivatization reagent for the determination of various amines in waste water and surface water at the sub-ppb level by gas chromatography-mass spectrometry.
Cobaltous Sulphate Heptahydrate AR 500g is used in the preparation of pigments, as well as in the manufacture of other cobalt salts, which is used in porcelains and glass
