Synthetic Route of 1603-91-4, An article , which mentions 1603-91-4, molecular formula is C4H6N2S. The compound – 4-Methylthiazol-2-amine played an important role in people’s production and life.
The invention relates to a new method of synthesizing thiabendazole, acetone and chlorine as the starting material synthetic monochloride, without separation can be directly with the thiourea obtained by reaction of 2 – amino – 4 – methyl thiazole, through diazotization reaction to obtain 4 – methyl thiazole, oxidation of thiazole – 4 – carboxylic acid, the final thiazole – 4 – carboxylic acid with O-phenylene diamine reaction to obtain the target product thiabendazole. The product of thiabendazole is a broad-spectrum anthelmintic, to roundworm, hook, whip, parasitic worm, the manure round nematodes and Trichinella spiralis infection have linking agent, also is a broad spectrum efficient bactericide, over the past ten years the wide as fruits and a plurality of fields of a fungicidal agent.
