Esomeprazole Impurity 23 CAS 1422063-97-5

Description

Compared with other compounds in its class, the molecular weight of 377.48 g/mol gives Esomeprazole Impurity 23 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Esomeprazole Impurity 23 (CAS 1422063-97-5) is a certified pharmaceutical impurity reference standard with the molecular formula C17H19N3O3S2 and a molecular weight of 377.48 g/mol.

Esomeprazole Impurity 23 (C17H19N3O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Esomeprazole Impurity 23 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.
