Used primarily as an intermediate in the synthesis of various organic compounds, it plays a crucial role in the production of pharmaceuticals, agrochemicals, and specialty chemicals. In the pharmaceutical industry, it is employed in the creation of active pharmaceutical ingredients (APIs) due to its reactive chloro and carboxylic acid groups. It is also utilized in the manufacture of herbicides and pesticides, contributing to effective crop protection solutions. Additionally, its application extends to the polymer industry, where it is involved in the production of specialty polymers and coatings, enhancing properties like durability and chemical resistance.
