Description
CATO supplies 3,4-Dimethyl-3-iodobenzophenone (CAS 951884-21-2), a certified reference material (molecular formula C15H13IO, MW 336.17 g/mol) for analytical method development and quality control.
The molecular framework of 3,4-Dimethyl-3-iodobenzophenone (C15H13IO) is characterized by a hydroxyl group, an ether linkage, iodine 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-Dimethyl-3-iodobenzophenone 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.
