Cefepime Impurity 1 CAS 120-94-5 chemical structure

Description

As a certified reference material (CRM), Cefepime Impurity 1 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.

CATO supplies Cefepime Impurity 1 (CAS 120-94-5), a pharmacopoeial impurity reference standard (molecular formula C5H11N, MW 85.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Cefepime Impurity 1 (C5H11N) contains an organic framework. Its physicochemical properties are representative of its class; 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.
