Chemical Structure

2-(4-Ethoxy-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 2282635-46-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Ethoxy-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane.

CATO supplies 2-(4-Ethoxy-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2282635-46-3), a certified reference material (molecular formula C14H19BF2O3, MW 284.11 g/mol) for analytical method development and quality control.

2-(4-Ethoxy-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C14H19BF2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-(4-Ethoxy-2,3-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
