(Z)-2-(2-(2-Chloro-3-(methoxymethoxy)phenyl)-1-fluorovinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2756454-48-3 chemical structure

Description

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.

(Z)-2-(2-(2-Chloro-3-(methoxymethoxy)phenyl)-1-fluorovinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2756454-48-3), molecular formula C16H21BClFO4 and molecular weight 342.60 g/mol, is a CATO reference standard with documented purity and traceability.

(Z)-2-(2-(2-Chloro-3-(methoxymethoxy)phenyl)-1-fluorovinyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C16H21BClFO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
