Chemical Structure
Description
The occurrence of 3,5-Difluoro-3-(1,3-dioxolan-2-yl)benzophenone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,5-Difluoro-3-(1,3-dioxolan-2-yl)benzophenone (CAS 898759-68-7), a certified reference material (molecular formula C16H12F2O3, MW 290.26 g/mol) for analytical method development and quality control.
Structurally, 3,5-Difluoro-3-(1,3-dioxolan-2-yl)benzophenone (C16H12F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 290.26 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
