Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.72 g/mol gives 3-Chloro-3-(1,3-dioxolan-2-yl)-4-fluorobenzophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Chloro-3-(1,3-dioxolan-2-yl)-4-fluorobenzophenone (CAS 898759-22-3), a certified reference material (molecular formula C16H12ClFO3, MW 306.72 g/mol) for analytical method development and quality control.
3-Chloro-3-(1,3-dioxolan-2-yl)-4-fluorobenzophenone (C16H12ClFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
