Used primarily in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. It serves as a key intermediate in the production of various biologically active compounds. The presence of both chlorine and iodine atoms on the benzene ring allows for versatile chemical transformations, making it valuable for cross-coupling reactions. Additionally, it is employed in the synthesis of herbicides and fungicides, contributing to crop protection. Its nitrile group further enhances its utility in creating complex molecules for medicinal chemistry.
