Description

p-Aminosalicylic Acid Sodium Salt is the sodium salt derivative of the well-known anti-tuberculosis agent, p-aminosalicylic acid. This compound is valued for its enhanced stability and solubility profile compared to the free acid form, making it a critical intermediate in pharmaceutical synthesis. It is primarily required by manufacturers in the pharmaceutical and fine chemical industries for the production of second-line anti-tuberculosis medications and other specialized organic compounds.

Application

• Pharmaceutical Intermediate: A key starting material or intermediate in the synthesis of anti-tuberculosis drugs and related pharmaceutical actives.
• Chemical Synthesis: Used as a building block in organic chemistry for the preparation of more complex molecules, particularly those containing salicylate and aniline functionalities.
• Research & Development: Employed in biochemical and pharmacological research for studying mycobacterial infections and developing new therapeutic agents.
• Reference Standard: Serves as a high-purity analytical standard in quality control laboratories for drug testing and method validation.
