Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-Ethoxy-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.
CATO supplies 2-(5-Ethoxy-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1445601-61-5), a certified reference material (molecular formula C14H19BF2O3, MW 284.11 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H19BF2O3, 2-(5-Ethoxy-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 284.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
