Acetyl Salicyclic acid (ASA) is an acetyl derivative of salicylic acid and its common name is Aspirin. It is used in the treatment of pain, fever, and inflammation. Aspirin or acetylsalicylic acid is perhaps the most commonly used analgesic and antipyretic medication worldwide. Reference standards of Acetylsalicylic Acid API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
