Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and anti-tuberculosis agents such as derivatives of 4-aminosalicylic acid (PAS). Its N-acetylated structure enhances chemical stability and may reduce gastrointestinal irritation compared to non-acetylated salicylates, making it suitable for formulations aimed at improving patient tolerability. It has been investigated for potential direct applications in anti-TB therapy with modified pharmacokinetics. Additionally, it serves as a building block in organic synthesis for creating derivatives with antimicrobial and antioxidant properties.
