About Omeprazole-13C,d3

Omeprazole-13C,d3 is a stable isotope labelled analogue related to Omeprazole carrying the CAS registry number 1261395-28-1. With the molecular formula C17H19N3O3S, it has a molar mass of 349.4 g/mol. The IUPAC name is 2-[(4-methoxy-3,5-dimethyl-2-pyridinyl)methylsulfinyl]-6-(trideuterio(113C)methoxy)-1H-benzimidazole. Common synonyms include Omeprazole (Benzimidazole 5-Methoxy-13CD3).

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, Omeprazole-13C,d3 is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
