metobenzuron

Production Methods

Metobenzuron is commercially produced by a process that involves preparing a 3,4-dihydro-2-methoxy-2,4,4-trimethylchroman-7-ol intermediate, which is then etherified with 4-hydroxyphenyl-N-methoxy-N-methylurea under controlled conditions to yield the final compound: N′-[4-[(3,4-dihydro-2-methoxy-2,4,4-trimethyl-2H-1-benzopyran-7-yl)oxy]phenyl]-N-methoxy-N-methylurea. This process typically uses organic solvents and mild base catalysis to ensure selectivity and stability.

Mechanism of action

Contact, selective, a non-cyclic photophoshorylation inhibitor
