Chemical Structure
Description
As a certified reference material (CRM), 3-(5-Methyl-1,3,4-oxadiazol-2-yl)-4H-chromen-4-one 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.
CATO supplies 3-(5-Methyl-1,3,4-oxadiazol-2-yl)-4H-chromen-4-one (CAS 60723-59-3), a certified reference material (molecular formula C12H8N2O3, MW 228.20 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-(5-Methyl-1,3,4-oxadiazol-2-yl)-4H-chromen-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
