Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Ethyl-2-iodobenzophenone.
4-Ethyl-2-iodobenzophenone (CAS 951885-09-9), molecular formula C15H13IO and molecular weight 336.17 g/mol, is a CATO reference standard with documented purity and traceability.
4-Ethyl-2-iodobenzophenone (C15H13IO) contains a hydroxyl group, an ether linkage, iodine 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.
As a certified reference material (CRM), 4-Ethyl-2-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.
