Chemical Structure
Description
The occurrence of (3-Bromophenyl)(3,5-difluorophenyl)methanol is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3-Bromophenyl)(3,5-difluorophenyl)methanol (CAS 1273815-27-2), molecular formula C13H9BrF2O and molecular weight 299.11 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H9BrF2O, (3-Bromophenyl)(3,5-difluorophenyl)methanol contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 299.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
