Cefpirome Impurity 8 CAS 533-37-9 chemical structure

Description

CATO manufactures Cefpirome Impurity 8 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Cefpirome Impurity 8 (CAS 533-37-9), a pharmacopoeial impurity reference standard (molecular formula C8H9N, MW 119.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C8H9N, Cefpirome Impurity 8 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 119.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
