Description

4-Aminosalicylic Acid Calcium Salt is the calcium salt derivative of the important pharmaceutical intermediate 4-aminosalicylic acid. This compound is valued for its enhanced stability and handling properties compared to the free acid form, making it a critical component in specific therapeutic formulations. It is primarily utilized by manufacturers in the pharmaceutical and fine chemical industries for the synthesis of active pharmaceutical ingredients (APIs) and as a key intermediate in research and development.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of anti-tuberculosis agents and other therapeutic compounds.
• API Manufacturing: Used in the production of Active Pharmaceutical Ingredients (APIs) requiring a stable, bioavailable calcium salt form.
• Research & Development: Serves as a crucial reagent in medicinal chemistry research for developing new drug candidates.
• Fine Chemical Synthesis: Employed in multi-step organic syntheses to introduce the 4-aminosalicylate moiety.
• Chemical Reference Standard: Used as a certified reference material (CRM) for analytical method development and quality control in pharmaceutical labs.
