Description
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
Risperidone EP Impurity C ((S)-Isomer) (CAS 147663-01-2) is a certified pharmaceutical impurity reference standard with the molecular formula C23H27FN4O3 and a molecular weight of 426.48 g/mol.
Based on its molecular formula C23H27FN4O3, Risperidone EP Impurity C ((S)-Isomer) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 426.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Risperidone EP Impurity C ((S)-Isomer) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
