Description

Quinclorac-Methyl Ester is a key chemical intermediate primarily used in the synthesis of the selective herbicide Quinclorac. This compound matters for its role in producing effective crop protection agents that target broadleaf and grassy weeds in rice and turfgrass. Industrial manufacturers and agrochemical formulators need this high-purity intermediate to ensure the efficacy and consistency of their final herbicide products.

Application

• Primary Intermediate for the synthesis of the herbicide Quinclorac (3,7-dichloro-8-quinolinecarboxylic acid).
• Agrochemical Research & Development for creating novel formulations and studying structure-activity relationships.
• Production of Selective Herbicides used in rice paddies to control barnyard grass and other weeds.
• Turf Management formulations for weed control in lawns and golf courses.
• Manufacturing of Crop Protection Products for broadleaf weed control in various agricultural settings.
