Description
As a certified reference material (CRM), 3,4-Dichloro-2-ethylbenzophenone 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.
3,4-Dichloro-2-ethylbenzophenone (CAS 951885-03-3), molecular formula C15H12Cl2O and molecular weight 279.16 g/mol, is a CATO reference standard with documented purity and traceability.
3,4-Dichloro-2-ethylbenzophenone (C15H12Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
