Widely used as a primary treatment for tuberculosis by inhibiting the synthesis of mycolic acids, essential components of the cell wall in Mycobacterium tuberculosis, thereby preventing bacterial growth. It is often combined with other antitubercular drugs such as rifampicin, pyrazinamide, and ethambutol to enhance efficacy and prevent resistance. Additionally, it is employed in the synthesis of various hydrazone derivatives, which are explored for their potential antimicrobial and anticancer properties. In research, it serves as a reagent in organic synthesis and analytical chemistry for detecting and quantifying carbonyl compounds. Its role in preventing the spread of tuberculosis in high-risk populations has made it a critical component in global health programs. Use under medical supervision is recommended due to potential side effects such as hepatotoxicity or neurological symptoms.
