Description

Calcium 4-Aminosalicylate is the calcium salt of 4-aminosalicylic acid, a compound with significant therapeutic and industrial relevance. Its primary value lies in its role as a key intermediate in the synthesis of anti-tuberculosis agents and other pharmaceutical compounds. This product is essential for manufacturers in the pharmaceutical, fine chemical, and research sectors requiring a reliable, high-purity building block for complex syntheses.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of second-line anti-tuberculosis drugs, particularly para-aminosalicylic acid (PAS) and its derivatives.
• Fine Chemical Synthesis: Used as a versatile building block for creating complex organic molecules, including dyes and specialty chemicals.
• Research & Development: Serves as a standard or starting material in biochemical and pharmacological research, especially in studies related to mycobacterial infections.
• Chemical Reference Standard: Employed as a high-purity analytical standard for quality control and method validation in pharmaceutical laboratories.

Quality Control

Our Calcium 4-Aminosalicylate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality documentation, including detailed Certificates of Analysis (COA) that confirm identity, purity, and impurity profiles. The product is tested against in-house specifications developed for pharmaceutical intermediate applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term stability and to minimize degradation.
