Chemical Structure
Description
1-(2,3-Dichlorophenyl)-3,3-dimethylbutan-1-one (CAS 898764-84-6), molecular formula C12H14Cl2O and molecular weight 245.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2,3-Dichlorophenyl)-3,3-dimethylbutan-1-one (C12H14Cl2O) is characterized by a hydroxyl group, an ether linkage, 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 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.
As a certified reference material (CRM), 1-(2,3-Dichlorophenyl)-3,3-dimethylbutan-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.
