1-(3,4-Dichlorophenyl)-3-methylbutan-1-one CAS 904923-17-7

Description

Compared with other compounds in its class, the molecular weight of 231.12 g/mol gives 1-(3,4-Dichlorophenyl)-3-methylbutan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(3,4-Dichlorophenyl)-3-methylbutan-1-one (CAS 904923-17-7), molecular formula C11H12Cl2O and molecular weight 231.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-(3,4-Dichlorophenyl)-3-methylbutan-1-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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
