Chemical Structure
Description
CATO supplies (3,4-Dichlorophenyl)(3,4-dimethylphenyl)methanone (CAS 844885-34-3), a certified reference material (molecular formula C15H12Cl2O, MW 279.16 g/mol) for analytical method development and quality control.
The molecular framework of (3,4-Dichlorophenyl)(3,4-dimethylphenyl)methanone (C15H12Cl2O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (3,4-Dichlorophenyl)(3,4-dimethylphenyl)methanone 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.
