ORBENCARB

Uses

Orbencarb may be used as an analytical reference standard for the quantification of the analyte in water samples using cyclodextrin-modified micellar electro-kinetic chromatography (MEKC).', 'Refer to the productμs Certificate of Analysis for more information on a suitable instrument technique.

Definition

ChEBI: A monothiocarbamic ester that is carbamothioic S-acid substituted by two ethyl groups at the nitrogen atom and a 2-chlorobenzyl group at the the sulfur atom.

Metabolic pathway

When 14C-orbencarb is applied to the soil surface, plants absorb the radioactivity and orbencarb is rapidly transformed to water-soluble metabolites in the plants. The major metabolites identified are 2-chlorobenzyl alcohol and 2-chlorobenzoic acid both in free and conjugated forms, 2-chlorobenzyl sulfonic acid and methyl 2-chlorobenzylsulfone. Hydroxylated metabolites at the phenyl ring and N-vinyl metabolite are found in soybean plants. Orbencarb degrades more rapidly in soils under upland conditions than in soils under flooded conditions. The major degradation products in the soils are orbencarb sulfoxide, monodesmethylorbencarb, methyl-2- chlorobenzylsulfoxide, methyl-2-chlorobenzylsulfone, and 2-chlorobenzylsulfonic acid.
