Used as a reagent in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. It acts as a derivatizing agent for carbonyl compounds like aldehydes and ketones, forming crystalline derivatives that are useful in identification and purification processes. Commonly employed in the synthesis of sulfonyl hydrazones and in the development of bioactive molecules, including antimicrobial and antitumor agents. Also utilized in analytical chemistry for the detection and characterization of carbonyl-containing compounds due to its ability to form stable, well-defined adducts.
