4-(5-chlorothiophen-2-yl)butan-2-one CAS 1099653-15-2

Description

Compared with other compounds in its class, the molecular weight of 188.67 g/mol gives 4-(5-chlorothiophen-2-yl)butan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(5-chlorothiophen-2-yl)butan-2-one (CAS 1099653-15-2), molecular formula C8H9ClOS and molecular weight 188.67 g/mol, is a CATO reference standard with documented purity and traceability.

4-(5-chlorothiophen-2-yl)butan-2-one (C8H9ClOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
