Used primarily as an intermediate in the synthesis of various organic compounds, particularly in the production of pharmaceuticals and agrochemicals. It plays a key role in the manufacture of active ingredients for pesticides and herbicides, contributing to crop protection and pest management. Additionally, it is utilized in the development of specialty chemicals, including dyes and pigments, due to its reactive chloromethyl group. Its application extends to research and development in organic chemistry, where it serves as a building block for complex molecules.
