Acetylsalicylic Acid EP Impurity A is a specified related substance defined in the European Pharmacopoeia (EP) for the quality control of acetylsalicylic acid (aspirin). It is a known degradation or process-related impurity that may form during the synthesis or storage of aspirin. The EP includes this impurity as a reference standard to help manufacturers identify and quantify it using analytical techniques such as HPLC, ensuring that acetylsalicylic acid meets established purity, safety, and quality requirements.
