Used primarily in the pharmaceutical industry as an intermediate in the synthesis of various active pharmaceutical ingredients (APIs). It plays a role in the development of drugs targeting inflammatory and autoimmune diseases due to its sulfonyl group, which is often involved in modulating biological activity. Additionally, it is utilized in research settings for studying enzyme inhibition and receptor interactions, particularly in pathways related to inflammation and immune response. Its hydrochloride form enhances solubility, making it suitable for use in aqueous-based formulations and laboratory experiments.
