Chemical Structure
Description
CATO supplies 1-(4-(2,5-Difluorophenoxy)phenyl)ethan-1-ol (CAS 1478075-02-3), a certified reference material (molecular formula C14H12F2O2, MW 250.24 g/mol) for analytical method development and quality control.
1-(4-(2,5-Difluorophenoxy)phenyl)ethan-1-ol (C14H12F2O2) contains a carboxylic acid group, 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
