Omeprazole Impurity 24 Sodium Salt CAS 161796-77-6

Description

The occurrence of Omeprazole Impurity 24 Sodium Salt is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Omeprazole Impurity 24 Sodium Salt (CAS 161796-77-6), a pharmacopoeial impurity reference standard (molecular formula C17H18N3O3SNa, MW 367.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Omeprazole Impurity 24 Sodium Salt (C17H18N3O3SNa) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.5, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 367.40 g/mol, it falls into the moderately-high-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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
