Used as an intermediate in the synthesis of herbicides, particularly phenoxy-type plant growth regulators like 2,4-D and MCPA. It plays a key role in agricultural chemistry for controlling broadleaf weeds in crops such as cereals, corn, and turf. Its sodium salt form improves water solubility, making it suitable for liquid formulations in crop protection products. Also utilized in the production of certain pharmaceuticals and organic synthesis where a phenoxyacetic acid derivative is required.
