What is 2,3,6-TRICHLOROBENZOIC ACID?
Chemical properties
A solid.
The Uses of 2,3,6-TRICHLOROBENZOIC ACID
An all-purpose, non-selective, pre-emergent and early post-emergent herbicide.
The Uses of 2,3,6-TRICHLOROBENZOIC ACID
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.
Hazard
Poison; moderately toxic.
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.
