Description

Sodium 4-Aminosalicylate is the sodium salt form of 4-aminosalicylic acid, a key pharmaceutical intermediate. This compound is valued for its stability and solubility, making it a critical building block in the synthesis of anti-tuberculosis agents and other active pharmaceutical ingredients (APIs). It is primarily required by manufacturers in the pharmaceutical, fine chemical, and research sectors for the development of targeted therapeutic compounds.

Application

• Pharmaceutical Intermediate: A primary precursor in the synthesis of second-line anti-tuberculosis drugs, particularly para-aminosalicylic acid (PAS) and its derivatives.
• API Synthesis: Used as a key starting material or intermediate in the production of various other active pharmaceutical ingredients requiring the aminosalicylate moiety.
• Chemical Research: Serves as a reagent in organic synthesis and medicinal chemistry research for developing new molecular entities.
• Biochemical Studies: Employed in laboratory studies investigating folate metabolism and related biochemical pathways.
• Veterinary Pharmaceuticals: Potential use in formulating treatments for bacterial infections in animals.
