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.
CATO supplies 3-((2,4-Dinitrophenyl)thio)-5H-[1,2,4]triazino[5,6-b]indole (CAS 1024558-91-5), a certified reference material (molecular formula C15H8N6O4S, MW 368.33 g/mol) for analytical method development and quality control.
3-((2,4-Dinitrophenyl)thio)-5H-[1,2,4]triazino[5,6-b]indole (C15H8N6O4S) 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.
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.
