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.
2-{[2-(4-ethoxyphenyl)-5-methyl-1,3-oxazol-4-yl]methyl}-8-(piperidine-1-sulfonyl)-2H,3H-[1,2,4]triazolo[4,3-a]pyridin-3-one (CAS 1707392-09-3), molecular formula C24H27N5O5S and molecular weight 497.57 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-{[2-(4-ethoxyphenyl)-5-methyl-1,3-oxazol-4-yl]methyl}-8-(piperidine-1-sulfonyl)-2H,3H-[1,2,4]triazolo[4,3-a]pyridin-3-one (C24H27N5O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. 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).
CATO manufactures 2-{[2-(4-ethoxyphenyl)-5-methyl-1,3-oxazol-4-yl]methyl}-8-(piperidine-1-sulfonyl)-2H,3H-[1,2,4]triazolo[4,3-a]pyridin-3-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
