Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antitubercular drugs. It serves as a building block for active pharmaceutical ingredients due to its reactive amino and hydroxyl functional groups, which allow for easy modification and derivatization. Also employed in the preparation of heterocyclic compounds with potential biological activity, including antimicrobial and antiviral agents. Its structural features make it valuable in medicinal chemistry for designing new drug candidates targeting central nervous system disorders and infectious diseases.
