Pipotiazine is an antipsychotic medication used to treat schizophrenia and other psychotic disorders. However, during the manufacturing process, impurities may be introduced which can affect the safety and efficacy of the drug. These impurities need to be identified and quantified to ensure the drug is safe for use. Common pipotiazine impurities include degradation products, residual solvents, and other organic compounds. Analytical techniques such as HPLC, GC-MS, and NMR spectroscopy are used to identify and quantify these impurities.
