Chemical Structure
Description
CATO supplies (4-Chloro-2,5-difluorophenyl)(cyclopentyl)methanone (CAS 1443354-45-7), a certified reference material (molecular formula C12H11ClF2O, MW 244.66 g/mol) for analytical method development and quality control.
Structurally, (4-Chloro-2,5-difluorophenyl)(cyclopentyl)methanone (C12H11ClF2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 244.66 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (4-Chloro-2,5-difluorophenyl)(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.
