Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure supports the formation of heterocyclic compounds with therapeutic activity. It also finds use in agrochemicals for enhancing stability and reactivity in certain crop protection agents. Additionally, it serves as a building block in organic synthesis where sulfonamide functionality is required, contributing to improved pharmacokinetic properties in drug design.
