Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2-Chloro-6-fluorophenyl)(cyclopentyl)methanone (CAS 1443342-98-0), molecular formula C12H12ClFO and molecular weight 226.67 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, (2-Chloro-6-fluorophenyl)(cyclopentyl)methanone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 226.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (2-Chloro-6-fluorophenyl)(cyclopentyl)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.
