Chemical Structure

3-Methyl-2-buten-1-yl thiolacetate CAS 33049-93-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 144.23 g/mol gives 3-Methyl-2-buten-1-yl thiolacetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Methyl-2-buten-1-yl thiolacetate (CAS 33049-93-3) is a high-purity analytical reference standard with the molecular formula C7H12OS and a molecular weight of 144.23 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-Methyl-2-buten-1-yl thiolacetate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
