Functional uses

  • Biocide

How it is made

Bromacil is produced by reaction of isopropyl isocyanate with methyl 3-aminocrotonate, followed by cyclization in sodium hydroxide at elevated temperature, and bromination in acetic acid.

Bromination of 3-sec-butyl-6-methyluracil

Bromacil is manufactured by the reaction of phosgene and ammonia with sec-butylamine to produce sec-butylurea, which reacts with ethylacetoacetate to produce 3-sec-butyl-6-methyluracil, which is then brominated to produce bromacil.
