Esomeprazole Impurity 52 CAS 704910-88-3

Description

CATO manufactures Esomeprazole Impurity 52 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.

Esomeprazole Impurity 52 (CAS 704910-88-3) is a certified pharmaceutical impurity reference standard with the molecular formula C15H15N3OS and a molecular weight of 285.36 g/mol.

Based on its molecular formula C15H15N3OS, Esomeprazole Impurity 52 contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
