Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Difluoro-2'-(difluoromethoxy)-4'-(trifluoromethyl)biphenyl.
2,3-Difluoro-2'-(difluoromethoxy)-4'-(trifluoromethyl)biphenyl (CAS 1261588-08-2) is a high-purity analytical reference standard with the molecular formula C14H7F7O and a molecular weight of 324.19 g/mol.
2,3-Difluoro-2'-(difluoromethoxy)-4'-(trifluoromethyl)biphenyl (C14H7F7O) contains a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
