3625-57-8 Benzo(a)phenoxazin-7-ium, 5-amino-9-(diethylamino)-, sulfate (2:1) Bis(5-amino-9-(diethylamino)benzo(a)phenoxazin-7-ium) sulphate 5H-Benzo(a)phenazoxazine, 9-(diethylamino)-5-imino-, sulfate (2:1) EINECS 222-832-5 Nile Blue A sulfate Nile Blue sulfate NSC 3250 NSC 34914 (CAS 3625-57-8) is a high-purity analytical reference standard with the molecular formula C20H30N3OO4S and a molecular weight of 424.54 g/mol.
The molecular framework of 3625-57-8 Benzo(a)phenoxazin-7-ium, 5-amino-9-(diethylamino)-, sulfate (2:1) Bis(5-amino-9-(diethylamino)benzo(a)phenoxazin-7-ium) sulphate 5H-Benzo(a)phenazoxazine, 9-(diethylamino)-5-imino-, sulfate (2:1) EINECS 222-832-5 Nile Blue A sulfate Nile Blue sulfate NSC 3250 NSC 34914 (C20H30N3OO4S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
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.
