The occurrence of 2-(2-Ethoxy-3,4-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(2-Ethoxy-3,4-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2877757-14-5), molecular formula C14H19BF2O3 and molecular weight 284.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-Ethoxy-3,4-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C14H19BF2O3) 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.
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-(2-Ethoxy-3,4-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.
