Description
CATO manufactures 3,5-Difluoro-4-ethoxybenzophenone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
3,5-Difluoro-4-ethoxybenzophenone (CAS 951884-68-7) is a high-purity analytical reference standard with the molecular formula C15H12F2O2 and a molecular weight of 262.25 g/mol.
3,5-Difluoro-4-ethoxybenzophenone (C15H12F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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.
