Description

p-Aminosalicylic Acid Magnesium Salt is a magnesium salt derivative of the well-known anti-tuberculosis agent, p-aminosalicylic acid. This compound is valued for its enhanced stability and bioavailability compared to the free acid form, making it a critical intermediate in advanced pharmaceutical synthesis. It is primarily utilized by manufacturers in the pharmaceutical industry for the development of anti-mycobacterial drugs and other specialized medicinal formulations.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of second-line anti-tuberculosis medications and other antimicrobial agents.
• Active Pharmaceutical Ingredient (API) Synthesis: Used in the production of finished dosage forms requiring the p-aminosalicylic acid moiety with improved handling properties.
• Research & Development: Serves as a standard or reagent in biochemical and pharmacological research targeting mycobacterial infections.
• Veterinary Pharmaceuticals: Employed in the formulation of treatments for bacterial infections in animals.
