Chemical Structure

(S)-2-Methylbutane-1-thiol CAS 20089-07-0 chemical structure

Description

(S)-2-Methylbutane-1-thiol (CAS 20089-07-0) is a high-purity analytical reference standard with the molecular formula C5H12S and a molecular weight of 104.21 g/mol.

Based on its molecular formula C5H12S, (S)-2-Methylbutane-1-thiol contains sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 104.21 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.
