7-Amino-4-hydroxy-3-[[5-hydroxy-6-(phenylazo)-7-sulfo-2-naphthalenyl]azo]-2-naphthalenesulfonic acid disodium salt CAS 6227-02-7 chemical structure

Description

The occurrence of 7-Amino-4-hydroxy-3-[[5-hydroxy-6-(phenylazo)-7-sulfo-2-naphthalenyl]azo]-2-naphthalenesulfonic acid disodium salt is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Amino-4-hydroxy-3-[[5-hydroxy-6-(phenylazo)-7-sulfo-2-naphthalenyl]azo]-2-naphthalenesulfonic acid disodium salt (CAS 6227-02-7) is a high-purity analytical reference standard with the molecular formula C26H17N5O8S2Na and a molecular weight of 614.56 g/mol.

Structurally, 7-Amino-4-hydroxy-3-[[5-hydroxy-6-(phenylazo)-7-sulfo-2-naphthalenyl]azo]-2-naphthalenesulfonic acid disodium salt (C26H17N5O8S2Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 614.56 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.
