The occurrence of 5-Chloro-1-(3-fluoro-4-methylphenyl)-1-oxopentane is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Chloro-1-(3-fluoro-4-methylphenyl)-1-oxopentane (CAS 898761-27-8) is a high-purity analytical reference standard with the molecular formula C12H14ClFO and a molecular weight of 228.69 g/mol.
5-Chloro-1-(3-fluoro-4-methylphenyl)-1-oxopentane (C12H14ClFO) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 5-Chloro-1-(3-fluoro-4-methylphenyl)-1-oxopentane 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.
