Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves in the preparation of active ingredients in certain herbicides and plant growth regulators due to its ability to modify biological activity when incorporated into larger molecules. Also utilized in the development of fragrances and flavoring agents, where it contributes ester-like, fruity notes. Its chlorinated aromatic structure makes it suitable for substitution reactions in organic synthesis, particularly in the formation of more complex phenylacetic acid derivatives.
