Used primarily in organic synthesis, it serves as a key intermediate in the production of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs). It is also employed in the creation of agrochemicals, contributing to the synthesis of herbicides and pesticides. Additionally, it finds application in polymer chemistry, where it is utilized to modify or enhance the properties of certain polymers. Its isocyanate group makes it valuable for forming urethane linkages, which are essential in polyurethane production.
