Ceftizoxime Open-ring decarboxylation Dimer Impurity 57 CAS CATO-C4X-179357

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ceftizoxime Open-ring decarboxylation Dimer Impurity 57.

CATO supplies Ceftizoxime Open-ring decarboxylation Dimer Impurity 57 (CAS CATO-C4X-179357), a pharmacopoeial impurity reference standard (molecular formula C25H28N10O9S4, MW 740.81 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ceftizoxime Open-ring decarboxylation Dimer Impurity 57 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 740.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Ceftizoxime Open-ring decarboxylation Dimer Impurity 57 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.
