Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 284.11 g/mol gives 1-[2,6-Difluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]ethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-[2,6-Difluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]ethanol (CAS 1858215-82-3), a certified reference material (molecular formula C14H19BF2O3, MW 284.11 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1-[2,6-Difluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]ethanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
