Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. It serves as a building block in agrochemicals for developing herbicides and plant growth regulators. Also utilized in the preparation of specialty polymers and liquid crystals due to its aromatic and functional group compatibility. Its carboxylic acid and chlorine substituent allow for easy derivatization in multi-step organic syntheses.
