Uses

Different sources of media describe the Uses of 50-31-7 differently. You can refer to the following data:
1. An all-purpose, non-selective, pre-emergent and early post-emergent herbicide.
2. Systemic growth-regulator herbicide used for postemergence control of broad-leaved perennial and annual weeds in cereals and grass seed crops.

Definition

A substituted benzoic acid that is a potent synthetic auxin.

Safety Profile

Poison by intraperitoneal route.Moderately toxic by ingestion and subcutaneous routes.When heated to decomposition it emits toxic fumes ofClí. Used as an herbicide.

Environmental Fate

Photolytic. Plimmer (1970) postulated that the irradiation of 2,3,6-trichlorobenzoic acid in methanol will undergo dechlorination forming 2,3-, 2,6- and 3,6-dichlorobenzoic acids. Further irradiation may yield 2- and 3-chlorobenzoic acids which may ultimately form benzoic acid (Plimmer, 1970).Chemical/Physical. Reacts with alkalies and amines forming water-soluble salts.

Carboxylation of C-H bonds using N -heterocyclic carbene gold(I) complexes

A highly efficient [(NHC)AuI]-based (NHC = N-heterocyclic carbene) catalytic system for the carboxylation of aromatic and heteroaromatic C-H bonds was developed. The significant base strength of the Au-OH species is at the origin of the activation process and permits the facile functionalization of C-H bonds without the use of other organometallic reagents.
