8-Amino-1,6-naphthalenedisulfonic acid sodium salt CAS 129-91-9

Description

The molecular framework of 8-Amino-1,6-naphthalenedisulfonic acid sodium salt (C10H9NO6S2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

8-Amino-1,6-naphthalenedisulfonic acid sodium salt (CAS 129-91-9) is a high-purity analytical reference standard with the molecular formula C10H9NO6S2 and a molecular weight of 303.31 g/mol.

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.
