Chemical Structure
Description
As a certified reference material (CRM), 1-(3,4-Dichlorophenyl)-3-methylbutan-2-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-(3,4-Dichlorophenyl)-3-methylbutan-2-one (CAS 1181454-72-7) is a high-purity analytical reference standard with the molecular formula C11H12Cl2O and a molecular weight of 231.12 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-(3,4-Dichlorophenyl)-3-methylbutan-2-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 231.12 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.
