Used primarily as an intermediate in organic synthesis, particularly in the preparation of sulfonamide derivatives with biological activity. It reacts readily with amines to form pyrazole-containing sulfonamides, which are of interest in pharmaceutical research due to their potential as anti-inflammatory, antimicrobial, and anticancer agents. Its structure allows for easy incorporation into more complex molecules, making it valuable in the development of new drug candidates. Also employed in agrochemical synthesis for creating novel pesticides and herbicides with improved selectivity and efficacy.
