Chemical Structure

2-methylprop-1-ene-1-thiol CAS 5954-69-8 chemical structure

Description

2-methylprop-1-ene-1-thiol (CAS 5954-69-8), molecular formula C4H8S and molecular weight 88.17 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H8S, 2-methylprop-1-ene-1-thiol contains sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 88.17 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.
