Chemical Structure

1-(Thiophen-3-yl)propan-1-one CAS 51179-52-3 chemical structure

Description

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1-(Thiophen-3-yl)propan-1-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.20 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).

1-(Thiophen-3-yl)propan-1-one (CAS 51179-52-3), molecular formula C7H8OS and molecular weight 140.20 g/mol, is a CATO reference standard with documented purity and traceability.

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.
