Used in the synthesis of antitubercular drugs, particularly as an intermediate in the production of isonicotinic acid derivatives. It plays a role in developing compounds that inhibit bacterial cell wall formation, specifically targeting Mycobacterium tuberculosis. Its structure allows for modification to enhance drug stability, bioavailability, and activity against drug-resistant strains. Also investigated for potential use in central nervous system agents due to its ability to cross the blood-brain barrier.
