Chemical Structure
Description
As a certified reference material (CRM), 5-Hydroxy Omeprazole 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.
5-Hydroxy Omeprazole (CAS 92340-57-3), molecular formula C17H19N3O4S and molecular weight 361.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-Hydroxy Omeprazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
