Chemical Structure

1,2-Ethanedithiol CAS 540-63-6 chemical structure

Description

Owing to sulfur-containing functionality, 1,2-Ethanedithiol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 94.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

CATO supplies 1,2-Ethanedithiol (CAS 540-63-6), a certified reference material (molecular formula C2H6S2, MW 94.20 g/mol) for analytical method development and quality control.

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.
