Description
CATO supplies 2-(4-((4-Bromo-2-fluorophenoxy)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2246646-40-0), a certified reference material (molecular formula C19H21BBrFO3, MW 407.08 g/mol) for analytical method development and quality control.
Based on its molecular formula C19H21BBrFO3, 2-(4-((4-Bromo-2-fluorophenoxy)methyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane contains a steroid core, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 407.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
