Chemical Structure
Description
As a certified reference material (CRM), Prednisolone Impurity 64 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Prednisolone Impurity 64 (CAS 24808-87-5) is a certified pharmaceutical impurity reference standard with the molecular formula C25H30O8 and a molecular weight of 458.50 g/mol.
Based on its molecular formula C25H30O8, Prednisolone Impurity 64 contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 458.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
