Used as a key intermediate in organic synthesis, particularly in the preparation of sulfonate-based functional materials. It serves in the modification of polymers to enhance water solubility and ionic conductivity, making it valuable in the development of specialty chemicals for electrochemical applications. Commonly employed in the synthesis of surfactants and surface-active agents due to its amphiphilic characteristics. Also utilized in click chemistry protocols where sulfonate groups are needed to improve compound stability and reactivity under aqueous conditions.
