Description
As a certified reference material (CRM), 4-Desmethoxy Omeprazole-d3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-Desmethoxy Omeprazole-d3 (CAS 1794759-05-9), molecular formula C16H14D3N3O2S and molecular weight 318.41 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H14D3N3O2S, 4-Desmethoxy Omeprazole-d3 contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 318.41 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
