Chemical Structure

S-Sodium Ethanethiosulfonate CAS 31999-88-9 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 S-Sodium Ethanethiosulfonate.

CATO supplies S-Sodium Ethanethiosulfonate (CAS 31999-88-9), a certified reference material (molecular formula C2H5O2S2Na, MW 148.17 g/mol) for analytical method development and quality control.

Based on its molecular formula C2H5O2S2Na, S-Sodium Ethanethiosulfonate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 148.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
