Description
As a certified reference material (CRM), 1-Chloro-4-(chloro(4-fluorophenyl)methyl)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.
1-Chloro-4-(chloro(4-fluorophenyl)methyl)benzene (CAS 64583-39-7), molecular formula C13H9Cl2F and molecular weight 255.11 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/chlorine substitution, an aromatic ring system, 1-Chloro-4-(chloro(4-fluorophenyl)methyl)benzene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 255.11 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.
