Pharmaceutical Intermediates

1-Propanesulfonyl chloride is mainly used as intermediate of medicine and pesticide.

Diphenyl carbonate, white crystalline solid. Insoluble in water, soluble in hot ethanol, benzene, ether, carbon tetrachloride, glacial acetic acid and other organic solvents. Diphenyl carbonate is mainly used to synthesize methyl isocyanate in pesticides, and then to prepare carbamate insecticide carbofuran. In addition, it is mainly used in the plastic industry to manufacture polyaryl carbonate and p-hydroxybenzoic acid polyester, monoisocyanate and diisocyanate. Plastic plasticizers can also be prepared. Used as solvent and heat carrier in chemical production.

2,2-Dibromo-2-cyanoacetamide is a white crystal, soluble in general organic solvents (such as acetone, benzene, dimethylformamide, ethanol, polyethylene glycol, etc.), slightly soluble in water. Its aqueous solution is relatively stable in acidic condition and easy to hydrolyze in alkaline condition. The product is a broad-spectrum and efficient biocide. Its molecules can quickly penetrate the cell membrane of microorganisms, act on certain protein groups, and make the normal redox termination of cells, thus causing cell death. In addition, its molecules can selectively bromine or oxidize the special enzyme metabolites in microorganisms, resulting in the death of microorganisms. It is mainly used as bactericide and algaecide to prevent bacteria and algae from growing in water for paper industry, industrial cooling water, air conditioning water, lubricating oil for metalworking, water emulsion, pulp, wood, plywood and coating, and fiber.

N-Methylbenzylamine is a phenylmethylamine compound, which exists in carrot and can be used as a potential biomarker. It is a colorless to light yellow liquid. It is soluble in organic solvents and has the odor of benzylamine. It can be used in pharmaceutical intermediates, organic solvents, dye production and other organic synthesis.

Often used as pharmaceutical intermediates.
