Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 416.51 g/mol gives Methylprednisolone impurity 94 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methylprednisolone impurity 94 (CAS 86401-94-7), a pharmacopoeial impurity reference standard (molecular formula C24H32O6, MW 416.51 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, Methylprednisolone impurity 94 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 416.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Methylprednisolone impurity 94 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.
