Description

CATO supplies 2,7-Naphthalenedisulfonic acid, 4,4'-[1,4-phenylenebis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(2-sulfophenyl)azo]- 5-[[4-chloro-6-[4-[[4-chloro-6-[[8-hydroxy-3,6-disulfo-7-[(E)-(2-sulfophenyl)azo]-1-naphthyl]amino]-1,3,5-triazin-2-yl]amino]anilino]-1,3,5-triazin-2-yl]amino]-4-hydroxy-3-[(E)-(2-sulfophenyl)azo]naphthalene-2,7-disulfonic acid 61951-82-4 Reactive Red 120 (CAS 61951-82-4), a certified reference material (molecular formula C44H80Cl2N14O20S6, MW 1388.48 g/mol) for analytical method development and quality control.

Structurally, 2,7-Naphthalenedisulfonic acid, 4,4'-[1,4-phenylenebis[imino(6-chloro-1,3,5-triazine-4,2-diyl)imino]]bis[5-hydroxy-6-[(2-sulfophenyl)azo]- 5-[[4-chloro-6-[4-[[4-chloro-6-[[8-hydroxy-3,6-disulfo-7-[(E)-(2-sulfophenyl)azo]-1-naphthyl]amino]-1,3,5-triazin-2-yl]amino]anilino]-1,3,5-triazin-2-yl]amino]-4-hydroxy-3-[(E)-(2-sulfophenyl)azo]naphthalene-2,7-disulfonic acid 61951-82-4 Reactive Red 120 (C44H80Cl2N14O20S6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 1388.48 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
