Chemical Structure
Description
(3-Chloro-5-fluorophenyl)(4-fluorophenyl)methanol (CAS 844683-74-5) is a high-purity analytical reference standard with the molecular formula C13H9ClF2O and a molecular weight of 254.66 g/mol.
The molecular framework of (3-Chloro-5-fluorophenyl)(4-fluorophenyl)methanol (C13H9ClF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
