2-(3-Chloro-4,5-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1437779-87-7

Description

Compared with other compounds in its class, the molecular weight of 274.50 g/mol gives 2-(3-Chloro-4,5-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(3-Chloro-4,5-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1437779-87-7), a certified reference material (molecular formula C12H14BClF2O2, MW 274.50 g/mol) for analytical method development and quality control.

The molecular framework of 2-(3-Chloro-4,5-difluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C12H14BClF2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
