Chemical Structure
Description
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.
CATO supplies Remdesivir Impurity 47 (CAS CATO-C4X-210047), a pharmacopoeial impurity reference standard (molecular formula C34H41N6O8P, MW 692.70 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Remdesivir Impurity 47 (C34H41N6O8P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.5, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 692.70 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Remdesivir Impurity 47 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.
