Posaconazole lmpurity 179 CAS CATO-C4X-1208179

Description

The occurrence of Posaconazole lmpurity 179 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Posaconazole lmpurity 179 (CAS CATO-C4X-1208179), a pharmacopoeial impurity reference standard (molecular formula C37H39N5O4, MW 617.74 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C37H39N5O4, Posaconazole lmpurity 179 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 617.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Posaconazole lmpurity 179 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.
