Sodium 4-aminosalicylate dihydrate CAS#6018-19-5
Effective Anti-Tuberculosis Agent: Sodium p-aminosalicylate is widely used for the treatment of tuberculosis, offering a key therapeutic benefit in combating this disease.
High Solubility: It is highly soluble in water (956g/l), which ensures easy absorption and effective therapeutic action when used in medicinal formulations.
Stable Formulation: Available as a white crystalline powder, it maintains stability under controlled storage conditions (2-8°C), ensuring longevity and reliability in use.
Safe Handling: With moderate toxicity (Hazard Code: Xi), sodium p-aminosalicylate can be safely handled when following recommended safety protocols, ensuring user protection.
Sodium p-aminosalicylate, also known as sodium 4-amino-2-hydroxybenzoate dihydrate or PAS-Na, is a widely used anti-tuberculosis medication. It appears as a white or off-white crystalline powder with no odor, and a taste that is both sweet and salty.
It is highly soluble in water, slightly soluble in ethanol, but only sparingly soluble in acetone, and nearly insoluble in ether, chloroform, and benzene. The pH of a 2% aqueous solution ranges from 6.5 to 8. This solution is prone to decarbonation, which leads to the formation of m-aminophenol, so it is recommended to prepare the solution fresh when needed.
