7-Epimer Cefixime Methyl Ester CAS CATO-C4X-1139103 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Epimer Cefixime Methyl Ester.

CATO supplies 7-Epimer Cefixime Methyl Ester (CAS CATO-C4X-1139103), a certified reference material (molecular formula C17H17N5O7S2, MW 467.48 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 7-Epimer Cefixime Methyl Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 467.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 7-Epimer Cefixime Methyl Ester 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.
