Chemical Structure

Etapenem lmpurity 40 CAS 90822-24-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 390.35 g/mol gives Etapenem lmpurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Etapenem lmpurity 40 (CAS 90822-24-5, C17H18N4O7) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Etapenem lmpurity 40 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.35 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.

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 Etapenem lmpurity 40 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.
