Chemical Structure
Description
Owing to sulfur-containing functionality, 2,2-Bis(mercaptomethyl)propane-1,3-dithiol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
CATO supplies 2,2-Bis(mercaptomethyl)propane-1,3-dithiol (CAS 4720-60-9), a certified reference material (molecular formula C5H12S4, MW 200.41 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.
