Ethanethioic acid, S-2-propyn-1-yl ester CAS 13702-10-8

Description

The occurrence of Ethanethioic acid, S-2-propyn-1-yl ester is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethanethioic acid, S-2-propyn-1-yl ester (CAS 13702-10-8), molecular formula C5H6OS and molecular weight 114.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, Ethanethioic acid, S-2-propyn-1-yl ester is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
