4-Chlorophenyl acetate is primarily used in organic synthesis as an intermediate for the production of various pharmaceuticals, agrochemicals, and fine chemicals. It serves as a building block in the synthesis of more complex molecules, particularly those involving aromatic compounds. In the pharmaceutical industry, it is utilized in the development of drugs that require chlorophenyl groups for their biological activity. Additionally, it finds application in the manufacture of pesticides and herbicides, where it contributes to the creation of compounds that target specific pests or weeds. Its role in chemical research is also significant, as it is often employed in studies related to esterification reactions and the modification of aromatic structures.
