Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-2-(5-Ethylthiophen-2-yl)propan-1-ol (CAS 2762829-19-4), molecular formula C9H14OS and molecular weight 170.27 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, (S)-2-(5-Ethylthiophen-2-yl)propan-1-ol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.27 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).
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.
