Atracurium Impurity 21, identified by its CAS number 96946-43-9, is a chemical compound that is classified as an impurity associated with the neuromuscular blocking agent atracurium. This substance is typically characterized by its structural similarity to atracurium, which is a bisquaternary ammonium compound used in anesthesia to induce muscle relaxation during surgical procedures. Impurity 21 may exhibit properties such as a specific molecular weight and a defined chemical structure, which can influence its pharmacological activity and stability. The presence of impurities like Atracurium Impurity 21 in pharmaceutical formulations is closely monitored, as they can affect the efficacy and safety of the primary drug. Analytical techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry are often employed to identify and quantify such impurities in drug products. Understanding the characteristics and behavior of impurities is crucial for ensuring the quality and compliance of pharmaceutical preparations.
