Description
CATO supplies 2-(2,4-Dimethylphenyl)-2,2-difluoroethan-1-ol (CAS 1785274-59-0), a certified reference material (molecular formula C10H12F2O, MW 186.20 g/mol) for analytical method development and quality control.
2-(2,4-Dimethylphenyl)-2,2-difluoroethan-1-ol (C10H12F2O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring 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. 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.
