Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(4-Bromophenyl)-1-(3,5-difluorophenyl)propan-1-one (CAS 898762-00-0), molecular formula C15H11BrF2O and molecular weight 325.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(4-Bromophenyl)-1-(3,5-difluorophenyl)propan-1-one (C15H11BrF2O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 325.15 g/mol, it falls into the moderately-high-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).
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.
