Uses

Used in Agriculture:
2,3,6-Trichlorobenzoic acid is used as an all-purpose, non-selective, pre-emergent, and early post-emergent herbicide for controlling a wide range of weeds in various crops. Its non-selective nature allows it to target multiple weed species, making it a versatile option for farmers.
Used in Cereal and Grass Seed Crops:
In the cereal and grass seed crop industry, 2,3,6-trichlorobenzoic acid is utilized as a systemic growth-regulator herbicide for post-emergence control of broad-leaved perennial and annual weeds. Its ability to regulate plant growth helps maintain the health and productivity of cereal and grass seed crops by reducing competition from unwanted weeds.
Used in Chemical Synthesis:
Due to its unique chemical structure, 2,3,6-trichlorobenzoic acid can also be used as an intermediate in the synthesis of various organic compounds, including pharmaceuticals, agrochemicals, and other specialty chemicals. Its reactivity and functional group compatibility make it a valuable building block in the development of new molecules with specific applications.

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.

Pesticide-polymer systems prepared from vinyl monomers

Controlled release pesticide-polymer systems are prepared by the polymerization of vinyl monomers containing pendant pesticides. The vinyl monomers are prepared by reacting an acrylic acid derivative with a pesticide or a pesticide derivative having an active hydrogen. The pesticide-polymer systems prepared from the pesticide vinyl monomers release the active pesticide material by hydrolysis or chemical depolymerization under conditions of use.
