Compared with other compounds in its class, the molecular weight of 220.31 g/mol gives 1,3-Di(thiophen-2-yl)prop-2-en-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Di(thiophen-2-yl)prop-2-en-1-one (CAS 2309-48-0), molecular formula C11H8OS2 and molecular weight 220.31 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1,3-Di(thiophen-2-yl)prop-2-en-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
