Description

Compared with other compounds in its class, the molecular weight of 240.68 g/mol gives (5-chlorothiophen-2-yl)(4-fluorophenyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(5-chlorothiophen-2-yl)(4-fluorophenyl)methanone (CAS 57931-93-8), molecular formula C11H6ClFOS and molecular weight 240.68 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, (5-chlorothiophen-2-yl)(4-fluorophenyl)methanone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 240.68 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (5-chlorothiophen-2-yl)(4-fluorophenyl)methanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
