As a certified reference material (CRM), 1-(3-Chloro-4-fluorophenyl)pentan-1-one 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-(3-Chloro-4-fluorophenyl)pentan-1-one (CAS 1339657-45-2) is a high-purity analytical reference standard with the molecular formula C11H12ClFO and a molecular weight of 214.66 g/mol.
The molecular framework of 1-(3-Chloro-4-fluorophenyl)pentan-1-one (C11H12ClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
