Chemical Structure

3,6-Dithiabicyclo[3.1.0]hexane 3,3-dioxide CAS 81591-82-4 chemical structure

Description

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3,6-Dithiabicyclo[3.1.0]hexane 3,3-dioxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

3,6-Dithiabicyclo[3.1.0]hexane 3,3-dioxide (CAS 81591-82-4) is a high-purity analytical reference standard with the molecular formula C4H6O2S2 and a molecular weight of 150.22 g/mol.

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.
