Metolachlor ESA sodium salt (CAS 947601-85-6)

Metolachlor ESA sodium salt, also known as metolachlor ethanesulfonic acid, is a widely used herbicide in agricultural and industrial settings. It is a pre-emergence herbicide which is employed to prevent the germination and growth of weeds, as well as to control a variety of grasses and broadleaf weeds. It is often used in combination with other herbicides such as atrazine and simazine, and is also used in combination with fertilizer to improve crop yields. In scientific research, Metolachlor ESA sodium salt is often utilized to study the effects of herbicides on plants, other organisms, the environment, soil fertility, and water quality. It works to inhibit the growth of weeds by blocking the enzyme acetolactate synthase (ALS). This enzyme is responsible for the synthesis of branched-chain amino acids, which are essential for plant growth. Metolachlor ESA sodium salt has been found to reduce the amount of photosynthesis in plants as well as the amount of water and nutrients available to them. Furthermore, it reduces the amount of nitrogen and phosphorus in the soil.
