The molecular framework of 50662-99-2 Reactive yellow 2 Trisodium 4-((4-chloro-6-((4-sulphonatophenyl)amino)-1,3,5-triazin-2-yl)amino)-2-((1-(2,5-dichloro-4-sulphonatophenyl)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-4-yl)azo)benzenesulphonate Benzenesulfonic acid, 4-((4-chloro-6-((4-sulfophenyl)amino)-1,3,5-triazin-2-yl)amino)-2-(2-(1-(2,5-dichloro-4-sulfophenyl)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-4-yl)diazenyl)-, sodium salt (1:3) Benzenesulfonic acid, 4-((4-chloro-6-((4-sulfophenyl)amino)-1,3,5-triazin-2-yl)amino)-2-((1-(2,5-dichloro-4-sulfophenyl)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-4-yl)azo)-, trisodium salt Benzenesulfonic acid, 4-((4-chloro-6-((4-sulfophenyl)amino)-1,3,5-triazin-2-yl)amino)-2-((1-(2,5-dichloro-4-sulfophenyl)-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-4-yl)azo), trisodium salt EINECS 256-692-1 Cibacron Brilliant Yellow 3G-P (C25H43Cl3N9O10S3Na) is characterized by a salt form, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
