This compound is primarily used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its sulfonyl chloride group makes it highly reactive, enabling it to act as a building block for creating sulfonamide derivatives, which are essential in developing drugs with antibacterial, antiviral, or anti-inflammatory properties. Additionally, it finds application in the synthesis of dyes and pigments, where its structure contributes to the formation of complex organic molecules with specific color properties. Its versatility in chemical reactions also makes it valuable in research settings for developing novel compounds with potential industrial or medicinal uses.
