Chemical Structure
Description
As a certified reference material (CRM), Phosphoramidite Impurity 24 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.
As a process- or degradation-related impurity, Phosphoramidite Impurity 24 (CAS CATO-C4X-288624, C27H36N7O6P) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Structurally, Phosphoramidite Impurity 24 (C27H36N7O6P) contains a steroid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.5, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 585.59 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
