Chemical Structure

2-(2-Ethyl-4,5-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1698908-90-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2-(2-Ethyl-4,5-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1698908-90-5), a certified reference material (molecular formula C14H19BF2O2, MW 268.11 g/mol) for analytical method development and quality control.

The molecular framework of 2-(2-Ethyl-4,5-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C14H19BF2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 2-(2-Ethyl-4,5-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.
