Propyphenazone EP Impurity B CAS CATO-C4X-20342 chemical structure

Description

As a certified reference material (CRM), Propyphenazone EP Impurity B 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.

Propyphenazone EP Impurity B (CAS CATO-C4X-20342) is a certified pharmaceutical impurity reference standard with the molecular formula C14H18N2O and a molecular weight of 230.31 g/mol.

Propyphenazone EP Impurity B (C14H18N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
