Chemical Structure
Description
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.
5-Hydroxy Omeprazole Sodium Salt (CAS 1215629-45-0), molecular formula C17H18N3O4SNa and molecular weight 383.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Hydroxy Omeprazole Sodium Salt (C17H18N3O4SNa) contains a flavonoid 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 383.40 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.
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.
