Disodium 4,4'-Diazidostilbene-2,2'-disulfonate Tetrahydrate CAS 2718-90-3

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'-Diazidostilbene-2,2'-disulfonate Tetrahydrate.

Disodium 4,4'-Diazidostilbene-2,2'-disulfonate Tetrahydrate (CAS 2718-90-3), molecular formula C14H8N6Na2O6S2 and molecular weight 466.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H8N6Na2O6S2, Disodium 4,4'-Diazidostilbene-2,2'-disulfonate Tetrahydrate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 466.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
