Esomeprazol EP Impurity A(Omeprazole EP Impurity A) CAS 37052-78-1

Description

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO supplies Esomeprazol EP Impurity A(Omeprazole EP Impurity A) (CAS 37052-78-1), a pharmacopoeial impurity reference standard (molecular formula C8H8N2OS, MW 180.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Esomeprazol EP Impurity A(Omeprazole EP Impurity A) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.23 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.

CATO manufactures Esomeprazol EP Impurity A(Omeprazole EP Impurity A) 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.
