Used as a key intermediate in the synthesis of various heterocyclic compounds, particularly in the development of pharmaceuticals and agrochemicals. It serves as a building block for drugs with antimicrobial, antifungal, and antiviral properties due to its ability to form complexes with metal ions and participate in ring-forming reactions. Commonly employed in the preparation of thiadiazole-based derivatives that exhibit biological activity, including carbonic anhydrase inhibitors and anti-inflammatory agents. Also utilized in the design of corrosion inhibitors and in materials science for developing functional polymers and sensors. Its thiol and amino groups allow for easy modification, making it valuable in combinatorial chemistry and drug discovery.
