Chemical Structure

Omeprazole Impurity 30 CAS 727375-13-5 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 Omeprazole Impurity 30.

CATO supplies Omeprazole Impurity 30 (CAS 727375-13-5), a pharmacopoeial impurity reference standard (molecular formula C8H11NO2, MW 153.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Omeprazole Impurity 30 (C8H11NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 153.18 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures Omeprazole Impurity 30 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.
