Mesalazine impurity A

Mesalazine Impurity A is a chemical substance that is commonly used in the pharmaceutical industry as a reference standard for quality control purposes. It is also known as 2-amino-5-chlorobenzoic acid, and is a derivative of 5-aminosalicylic acid (5-ASA), which is the active ingredient in mesalazine. Mesalazine Impurity A plays an important role in the quality control of mesalazine-based medications, as it is used to determine the purity and potency of the drug. It is also used to identify and quantify impurities that may be present in mesalazine samples, which can affect the quality and safety of the medication. Chemically, Mesalazine Impurity A is a white to off-white crystalline powder that is soluble in water, ethanol and other organic solvents. Its chemical formula is C7H6ClNO2, and its molecular weight is 173.58 g/mol. When used in pharmaceutical applications, Mesalazine Impurity A should be handled with care, as it can be harmful if ingested, inhaled or absorbed through the skin. It should be stored in a cool, dry place, away from heat, light and moisture. In conclusion, Mesalazine Impurity A is an important reference standard in the pharmaceutical industry, and plays a crucial role in the quality control of mesalazine-based medications. Its chemical properties and usage information are important for pharmaceutical scientists and researchers who are involved in the development, production and testing of these medications.
