Chemical Structure

Sodium ethane-1,2-disulfonate CAS 5325-43-9 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 Sodium ethane-1,2-disulfonate.

CATO supplies Sodium ethane-1,2-disulfonate (CAS 5325-43-9), a certified reference material (molecular formula C2H4O6S2Na, MW 211.16 g/mol) for analytical method development and quality control.

Sodium ethane-1,2-disulfonate (C2H4O6S2Na) contains a sulfone group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
