Risperidone EP Impurity C (9-Hydroxy Risperidone, Paliperidone)(CAS: 144598-75-4)

Risperidone EP Impurity C, also known as 9-Hydroxy Risperidone or Paliperidone, is a metabolite of the antipsychotic drug risperidone. It has the chemical formula C18H22FN3O2 and is a white to pale yellow crystalline solid. This compound is commonly found in pharmaceutical impurity testing and is used to ensure the purity and safety of risperidone-based medications.

Risperidone EP Impurity C is primarily used in pharmaceutical quality control to detect and quantify impurities in risperidone formulations. It also serves as a reference standard in drug development, research, and analytical testing. Additionally, it is relevant in understanding drug metabolism and ensuring compliance with regulatory standards in the pharmaceutical industry.

Risperidone EP Impurity C is generally considered safe when handled according to standard laboratory procedures. However, as with any chemical, it should be treated with care, using appropriate personal protective equipment (PPE). Safety data sheets (SDS) recommend avoiding inhalation, ingestion, and skin contact, and proper disposal is necessary to comply with environmental and safety regulations.

Risperidone EP Impurity C should be stored in a cool, dry, and dark place, ideally at 2-8°C. It is recommended to keep it in a sealed container to prevent moisture and contamination. Avoid exposure to light and maintain controlled humidity levels to ensure stability and prolong shelf life.
