PRODUCT INTRODUCTION
description
Asulam is a carbamate ester that is methyl carbamate substituted by a (4-aminophenyl)sulfonyl group at the nitrogen atom. A dihydropteroate synthase inhibitor, it is used (normally as the corresponding sodium salt, asulam-sodium) as a herbicide, mainly for killing bracken. It has a role as an environmental contaminant, a xenobiotic, a herbicide, an agrochemical and an EC 2.5.1.15 (dihydropteroate synthase) inhibitor. It is a sulfonamide, a carbamate ester, a substituted aniline and a primary amino compound. It is a conjugate acid of an asulam(1-).
