Chemical Structure

Sodium 2-aminobenzene-1,4-disulfonate CAS 41184-20-7 chemical structure

Description

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.

Sodium 2-aminobenzene-1,4-disulfonate (CAS 41184-20-7) is a high-purity analytical reference standard with the molecular formula C6H5NO6S2Na and a molecular weight of 274.22 g/mol.

Owing to a carbohydrate-derived structure, an amide group, a sulfone group, Sodium 2-aminobenzene-1,4-disulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
