Chemical Structure
Description
N-Methyl Pantoprazole-d3 (Mixture of 1 and 3 isomers) (CAS 1190008-84-4) is a high-purity analytical reference standard with the molecular formula C17H14D3F2N3O4S and a molecular weight of 400.41 g/mol.
The molecular framework of N-Methyl Pantoprazole-d3 (Mixture of 1 and 3 isomers) (C17H14D3F2N3O4S) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
