Description
CATO supplies Sodium 4,4'-(3-(pyridin-2-yl)-1,2,4-triazine-5,6-diyl)dibenzenesulfonate (CAS 28048-33-1), a certified reference material (molecular formula C20H12N4O6S2Na, MW 491.45 g/mol) for analytical method development and quality control.
Structurally, Sodium 4,4'-(3-(pyridin-2-yl)-1,2,4-triazine-5,6-diyl)dibenzenesulfonate (C20H12N4O6S2Na) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 491.45 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
