General Information
Risperidone Impurities and Risperidone
Daicel Pharma synthesizes Risperidone impurity standards, including Risperidone N-oxide, 7-Fluoro Risperidone, 4-Fluoro Risperidone, 5-Fluoro Risperidone, and Des Fluoro Risperidone. They are significant in assessing the quality, stability, and biological safety of Risperidone. Daicel Pharma offers custom synthesis for Risperidone impurities and delivers them globally.
Risperidone [CAS: 106266-06-2] belongs to the pyridopyrimidine class and a second-generation antipsychotic (SGA) medicine. Risperidone treats schizophrenia and bipolar disorder.
Risperidone: Use and Commercial Availability
Risperidone treats schizophrenia in adults and manic or mixed episodes of bipolar disorder in children and adolescents aged 10 to 17. It controls symptoms of inappropriate behavior due to aggression and or psychosis. This drug is available under Perseris Kit, Risperdal, Rykindo, and Uzedy.
Risperidone Structure and Mechanism of Action 
The chemical name of Risperidone is 3-[2-[4-(6-Fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]ethyl]-6,7,8,9-tetrahydro-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one. Its chemical formula is C23H27FN4O2, and its molecular weight is approximately 410.5 g/mol.
The mechanism of action of Risperidone is unknown.
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.
