Chemical Structure
Description
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-((Z)-2-((Z)-2-(3-Methyl-5-oxo-1-(4-sulfophenyl)-1H-pyrazol-4(5H)-ylidene)ethylidene)benzo[d]oxazol-3(2H)-yl)propanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 469.47 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).
CATO supplies 3-((Z)-2-((Z)-2-(3-Methyl-5-oxo-1-(4-sulfophenyl)-1H-pyrazol-4(5H)-ylidene)ethylidene)benzo[d]oxazol-3(2H)-yl)propanoic acid (CAS 72796-92-0), a certified reference material (molecular formula C22H19N3O7S, MW 469.47 g/mol) for analytical method development and quality control.
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.
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.
