4-(Thiophen-2-yl)but-3-yn-2-one CAS 36710-95-9

Description

The occurrence of 4-(Thiophen-2-yl)but-3-yn-2-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(Thiophen-2-yl)but-3-yn-2-one (CAS 36710-95-9), molecular formula C8H6OS and molecular weight 150.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H6OS, 4-(Thiophen-2-yl)but-3-yn-2-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 150.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
