Intermediates

4-Chlorobenzaldehyde is also known as 4-chlorobenzaldehyde, with a molecular formula of C7H5ClO and a molecular weight of 140.567. This substance is mainly used in the manufacture of sedatives such as fenalol and aminophenolic acid and other pharmaceutical raw materials and intermediates. It is used in the manufacture of chlorocinnamon Aldehydes, weeding and killing enemies, etc.

It is used as pharmaceutical intermediates, caffeine and vitamin B, oil soluble couplers for color films and raw materials for 502 adhesives.

P-cresol is a raw material for manufacturing antioxidant 2,6-di-tert-butyl-p-cresol and rubber antioxidant. It can be used as cresol formaldehyde resin and plasticizer in plastic industry, disinfectant in medicine, pesticide raw material, intermediate of fungicide methyl-2,6-di-tert-butyl-p-cresol and insecticide Fenvalerate and etherthrin, and also an important basic raw material of dye clonidine sulfonic acid.

Colorless or yellow crystals or liquids with deliquescent properties. Soluble in ethanol and ether, soluble in water. It is chemically active and can undergo addition or condensation reactions with ammonia, amides, aldehydes, and carboxyl-containing compounds. Glyoxal is mainly used in the textile industry. As a fiber treatment agent, it can increase the shrinkage and wrinkle resistance of cotton, nylon and other fibers. It is a durable pressing finishing agent. In Japan, this use accounts for 80% of the total consumption of glyoxal. Glyoxal is an insoluble binder such as gelatin, animal glue, cheese, polyvinyl alcohol and starch. Glyoxal is also used in the leather industry and for making waterproof matches. Glyoxal is a raw material for organic synthesis. 2D-resin is obtained by heating and condensing acetaldehyde, urea and formaldehyde in the presence of sodium carbonate, which is used as fabric finishing agent; glyoxal reacts with formaldehyde and ammonium sulfate to synthesize imidazole, and then synthesize imidazole antifungal drug clotrimazole, Miconazole, etc.; Glyoxal and o-phenylenediamine cyclization to obtain benzopyrazine: it is an intermediate of the anti-tuberculosis drug pyrazinamide. Hydroxyphenyl acetic acid produced from glyoxal has been industrially produced in Japan and used as an intermediate for antibiotics and vitamin A series products. Glyoxal is also used in the synthesis of berberine hydrochloride and the sulfa drug sulfamethoxazine. It is also used in insecticides, deodorants, corpse preservatives, and sand curing agents.

This product is used as an intermediate of medicine and pesticide. It is an intermediate of fungicide benomyl.
