PRYNACHLOR Chemical Properties,Uses,Production

Uses

Prynachlor is a chloroacetanilide herbicide used in agriculture.

Production Methods

Prynachlor is commercially produced by a process that begins with N-phenylpropargylamine, which undergoes nucleophilic substitution with chloroacetyl chloride in the presence of a base such as triethylamine or sodium carbonate, to yield the final compound.

Mechanism of action

Selective, systemic action absorbed by germinating shoots. Lipid synthesis inhibitor.

Pesticide Type

Herbicide; Plant Growth Regulator
