Widely used as an intermediate in the synthesis of phenoxy herbicides, particularly for producing 2,4-D (2,4-dichlorophenoxyacetic acid) and related plant growth regulators. It functions as an ester precursor that can be hydrolyzed or modified to release the active herbicidal acid form. Due to its lipophilic nature, it can enhance penetration through plant cuticles when formulated in certain herbicide preparations. It is also employed in agricultural chemistry research for developing new auxin-type herbicides targeting broadleaf weeds in cereal crops. Its ester structure allows for better solubility in organic carriers, making it suitable for use in emulsifiable concentrate formulations.
