CATO supplies 2-(4-Isobutoxy-3-methoxybenzylidene)-6-phenyl-2H-thiazolo[3,2-b][1,2,4]triazine-3,7-dione (CAS 606956-86-9), a certified reference material (molecular formula C23H21N3O4S, MW 435.50 g/mol) for analytical method development and quality control.
2-(4-Isobutoxy-3-methoxybenzylidene)-6-phenyl-2H-thiazolo[3,2-b][1,2,4]triazine-3,7-dione (C23H21N3O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
