Description

Phosphinothricin is a potent, naturally occurring amino acid derivative that functions as a highly effective herbicide. Its primary value lies in its role as the active component of the non-selective herbicide glufosinate-ammonium, offering reliable weed control in agricultural and horticultural settings. This compound is essential for manufacturers in the agrochemical industry formulating broad-spectrum herbicides, as well as for researchers in plant biochemistry and molecular biology studying amino acid biosynthesis and herbicide resistance mechanisms.

Application

• Active Pharmaceutical Ingredient (API) in the synthesis of the herbicide glufosinate-ammonium.
• Key intermediate for the production of non-selective, post-emergence herbicides used in agriculture.
• Research chemical for studying the inhibition of glutamine synthetase in plants and microorganisms.
• Tool compound in biochemical assays to investigate nitrogen metabolism pathways.
• Reference standard for analytical method development and quality control in agrochemical manufacturing.
• Used in the development of genetically modified, herbicide-resistant crops (e.g., LibertyLink crops).
