ChEBI: The methyl ester of cloransulam. An inhibitor of acetohydroxyacid synthase (AHAS), it prevents the synthesis of amino acids in plants and is used as a herbicide for the control of post-emergence control of broad-leaved weeds in soybeans. It is not approved
for use within the European Area.
When 14C-cloransulam methyl is incubated with soils,
the degradation proceeds via the hydrolysis of the
ester group and O-de-ethylation on the
triazolopyrimidine ring to yield the three identified
metabolites, cloransulam, 5-hydroxycloransulam
methyl, and 5-hydroxycloransulam. These metabolites
are significantly less phytotoxic than the parent
herbicide.
