Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure allows for selective derivatization, making it valuable in creating biologically active compounds. Commonly employed in the development of herbicides and fungicides due to the presence of multiple chlorine atoms that enhance stability and target specificity. Also utilized in research settings for designing new molecules with antimicrobial or anti-inflammatory properties. The hydrochloride salt form improves solubility and handling in aqueous reaction systems.
