Chemical Structure

1,2-Butanedithiol CAS 16128-68-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 122.25 g/mol gives 1,2-Butanedithiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,2-Butanedithiol (CAS 16128-68-0), a certified reference material (molecular formula C4H10S2, MW 122.25 g/mol) for analytical method development and quality control.

The molecular framework of 1,2-Butanedithiol (C4H10S2) is characterized by sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
