Widely used as an intermediate in the synthesis of agricultural chemicals, particularly in the production of certain herbicides and plant growth regulators. It plays a key role in the manufacturing of 2,4-D, a common broadleaf herbicide, by serving as a precursor in chlorination and substitution reactions. Due to its reactivity, it is also employed in the development of specialty chemicals, including dyes and pharmaceuticals, where chlorinated aromatic structures are required. Its application is mainly confined to industrial settings due to its sensitivity to moisture and potential hazards.
