Pharmaceutical Intermediates

4-Cyano-3-trifluoromethylphenylisothiocyanate is an reagent used in the synthesis of thioxoimidazolidinones as potential anti-prostate cancer agents.Also used in the enzalutamide intermediate.

Rifamycin o (rifaximin EP impurity f) is an intermediate of rifaximin.

There are three stereoisomers of tartaric acid: tartaric acid, L-tartaric acid and racemic tartaric acid. Racemic tartaric acid is a mixture of the same amount of dextrosome and levosome whose optical activity counteracts each other. Racemates do not exist in nature and can be synthesized chemically. All kinds of tartaric acid are colorless crystals which are easily soluble in water. Tartaric acid is widely used as an Acidifier in beverages and other foods, similar to citric acid. Tartaric acid and tannin can be used as mordant of acid dyes, as well as in some developing and fixing operations in the photographic industry. Its iron salt is photosensitive, so it can be used to make blueprints. Tartaric acid can complex with many kinds of metal ions and can be used as cleaning agent and polishing agent for metal surface. Potassium and sodium tartrate (Rochelle salt) can be used as ferin reagent, medicine, laxative and diuretic, and intermediate of cinchofen. The crystal has piezoelectric properties and can be used in electronic industry. Therefore, this product is mainly used in beverage, candy, bread and gelatin as sour agent, biochemical reagent, racemic resolution agent and pharmaceutical resolution agent.

Zinc dibenzyldithiocarbamate is a useful analytical tool for the detection of copper in plant and biological tissues. It is also used to prepare dithiocarbamate ligands for stabilizing gold nanoparticles.

4-Aminobenzoic acid is one of the most important aromatic amino acids. It is an important part of essential substances for cell growth and division. It plays an irreplaceable role in the metabolism of life, and has a high content in yeast, liver, bran and malt. 4-Aminobenzoic acid can relieve anemia, viral anemia, stomatitis diarrhea and pregnancy anemia caused by red blood cell deficiency. 4-Aminobenzoic acid as the main component of high-efficiency nutrition compound vitamin B-100, can effectively improve the three major metabolism of human body, comprehensively fight fatigue and relieve pressure. 4-Aminobenzoic acid combined with penicillin or streptomycin can effectively improve the antibacterial effect. 4-Aminobenzoic acid is also an important fine chemical raw material. In medicine, it is a key intermediate for the synthesis of blood enriching agents folic acid, procoagulant and carboxyl benzamine. It is also used in the manufacture of drugs for rickets, rheumatism, arthritis and tuberculosis. In the cosmetics industry, it is an important intermediate of body sunscreen and hair growth agent; In organic chemical industry, it can be used to prepare various ester products, as resin modifier, and as special intermediate for synthesis of reactive dyes and azo dyes.
