1-(5-Chlorothiophen-2-yl)propan-2-one CAS 1249958-78-8

Description

Compared with other compounds in its class, the molecular weight of 174.65 g/mol gives 1-(5-Chlorothiophen-2-yl)propan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(5-Chlorothiophen-2-yl)propan-2-one (CAS 1249958-78-8), a certified reference material (molecular formula C7H7ClOS, MW 174.65 g/mol) for analytical method development and quality control.

The molecular framework of 1-(5-Chlorothiophen-2-yl)propan-2-one (C7H7ClOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
