Used as an intermediate in organic synthesis, particularly in the preparation of sulfonamide-based compounds with potential biological activity. It serves as a building block in the development of pharmaceuticals, leveraging the sulfonamide group's prevalence in drug molecules for its favorable pharmacokinetic properties. Commonly employed in condensation reactions to form imine derivatives that can be further modified for medicinal chemistry research. Also utilized in the study of crystallography and molecular structure due to its stable Schiff base formation.
