Chemical Structure
Description
Methyl 2-ethylÂthiopropionate (CAS 18673-13-7) is a high-purity analytical reference standard with the molecular formula C6H12O2S and a molecular weight of 148.22 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl 2-ethylÂthiopropionate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
