Chemical Structure

Disodium 4,4'-(2,4-dihydroxy-1,3-phenylene)bis(azo)bisnaphthalene-1-sulphonate CAS 5850-16-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Disodium 4,4'-(2,4-dihydroxy-1,3-phenylene)bis(azo)bisnaphthalene-1-sulphonate.

Disodium 4,4'-(2,4-dihydroxy-1,3-phenylene)bis(azo)bisnaphthalene-1-sulphonate (CAS 5850-16-8) is a high-purity analytical reference standard with the molecular formula C26H16N4O8S2Na and a molecular weight of 599.54 g/mol.

The molecular framework of Disodium 4,4'-(2,4-dihydroxy-1,3-phenylene)bis(azo)bisnaphthalene-1-sulphonate (C26H16N4O8S2Na) 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 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.

CATO manufactures Disodium 4,4'-(2,4-dihydroxy-1,3-phenylene)bis(azo)bisnaphthalene-1-sulphonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
