Prometon can be obtained by reacting propazine with methanol in the presence of sodium hydroxide or by reacting propazine with sodium methoxide .

properties

Prometon is a white, flammable solid that is very sparingly soluble in water.

use

Prometon is used as a herbicide against perennial grasses and leaf weeds. It works by inhibiting photosynthesis and influences photosystem II by competing with plastoquinone and thus disrupting electron transport processes. It was first approved in the United States in May 1959.
