Chemical Structure

4-methylthiolan-3-one CAS 50565-25-8 chemical structure

Description

4-methylthiolan-3-one (CAS 50565-25-8) is a high-purity analytical reference standard with the molecular formula C5H8OS and a molecular weight of 116.18 g/mol.

Based on its molecular formula C5H8OS, 4-methylthiolan-3-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 116.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
