Description
CATO supplies (Z)-Ceftizoxime Oxide Impurity 2 (CAS 79226-66-7), a pharmacopoeial impurity reference standard (molecular formula C13H13N5O6S2, MW 399.40 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of (Z)-Ceftizoxime Oxide Impurity 2 (C13H13N5O6S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures (Z)-Ceftizoxime Oxide Impurity 2 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.
