Evocalcet Impurity 9 CAS CATO-C4X-24859

Description

Compared with other compounds in its class, the molecular weight of 374.48 g/mol gives Evocalcet Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Evocalcet Impurity 9 (CAS CATO-C4X-24859), a pharmacopoeial impurity reference standard (molecular formula C24H26N2O2, MW 374.48 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Evocalcet Impurity 9 (C24H26N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 374.48 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Evocalcet Impurity 9 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.
