The occurrence of 4-(chloromethyl)-1-cyclopentyl-2-(trifluoromethyl)benzene is closely related to fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(chloromethyl)-1-cyclopentyl-2-(trifluoromethyl)benzene (CAS 957208-65-0) is a high-purity analytical reference standard with the molecular formula C13H20ClF3 and a molecular weight of 268.75 g/mol.
Owing to fluorine/chlorine substitution, 4-(chloromethyl)-1-cyclopentyl-2-(trifluoromethyl)benzene is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 268.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-(chloromethyl)-1-cyclopentyl-2-(trifluoromethyl)benzene 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.
