Methabenzthiazuron Use and Manufacturing

Methods of Manufacturing

In the presence of sodium carbonate, aniline reacts with CS2 to form sodium aniline thioformate, and then reacts with monomethylamine to prepare N-phenyl-N'-methylthiourea. Subsequent reaction with sulfuryl chloride generates 2-methylaminobenzothiazole. Finally, it reacts with methyl isocyanate to synthesize methyl benzothione. Or react 2-methylaminobenzothiazole with methylcarbamoyl chloride to produce methylbenzthione.

Uses

Selective herbicide.
