Description
CATO supplies 1-(2,5-Difluorophenyl)ethan-1-ol (CAS 3874-31-5), a certified reference material (molecular formula C8H8F2O, MW 158.15 g/mol) for analytical method development and quality control.
1-(2,5-Difluorophenyl)ethan-1-ol (C8H8F2O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
