Risperidone Impurities and Synthesis

Risperidone, an atypical antipsychotic medicine, may include impurities that impair efficacy and safety. Their presence may be due to the synthetic process1 or storage conditions.

Daicel Pharma provides a Certificate of Analysis (CoA) of Risperidone impurity standards, including Risperidone N-oxide, 7-Fluoro Risperidone, 4-Fluoro Risperidone, 5-Fluoro Risperidone, and Des Fluoro Risperidone. Our CoA is from a cGMP-compliant analytical facility and includes comprehensive characterization data, such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity2,3. If requested, we give additional characterization data, such as 13C-DEPT. Daicel Pharma can provide unknown Risperidone impurities or degradation products.
