Chemical Structure

5-O-Desmethyl Omeprazole-d3 Sulfide CAS 1189968-01-1 chemical structure

Description

The occurrence of 5-O-Desmethyl Omeprazole-d3 Sulfide is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, 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.

5-O-Desmethyl Omeprazole-d3 Sulfide (CAS 1189968-01-1), molecular formula C16H14D3N3O2S and molecular weight 318.41 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-O-Desmethyl Omeprazole-d3 Sulfide (C16H14D3N3O2S) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 318.41 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 5-O-Desmethyl Omeprazole-d3 Sulfide 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.
