Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 208.15 g/mol gives (S)-1-(3-Fluoro-5-(trifluoromethyl)phenyl)ethan-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (S)-1-(3-Fluoro-5-(trifluoromethyl)phenyl)ethan-1-ol (CAS 1567666-58-3), a certified reference material (molecular formula C9H8F4O, MW 208.15 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (S)-1-(3-Fluoro-5-(trifluoromethyl)phenyl)ethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
