Risperidone Impurity refers to chemical by-products or degradation products formed during the synthesis of risperidone, a second-generation antipsychotic. These impurities are critical for quality control in pharmaceutical manufacturing. The primary molecular formula is typically C23H27FN4O2 (Risperidone base), while specific impurity variants possess distinct CAS numbers assigned by regulatory bodies like USP or EP.
