Definition

ChEBI: Pyriminobac-methyl is a benzoate ester resulting from the formal condensation of the carboxy group of pyriminobac with methanol. It has a role as an EC 2.2.1.6 (acetolactate synthase) inhibitor and a herbicide. It is an aromatic ether, an oxime O-ether, a member of pyrimidines, a benzoate ester and a methyl ester. It is functionally related to a pyriminobac.
