Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators. Its sulfonyl chloride group readily reacts with amines to form sulfonamides, which are common structural motifs in bioactive molecules. It is also employed in the preparation of kinase inhibitors and other medicinal agents targeting neurological and psychiatric disorders. The methoxy group enhances selectivity in certain transformations, making it valuable in fine chemical synthesis and drug discovery research.
