Chemical Structure
Description
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.
261951-89-7 4 - Methoxy - 3 - (trifluoromethyl)benzyl bromide 4-(bromomethyl)-1-methoxy-2-(trifluoromethyl)benzene 4-(bromomethyl)-2-(trifluoromethyl)phenyl methyl ether 4-Bromomethyl-1-methoxy-2-trifluoromethyl-benzene benzene, 4-(bromomethyl)-1-methoxy-2-(trifluoromethyl)- (CAS 261951-89-7) is a high-purity analytical reference standard with the molecular formula C9H8BrF3O and a molecular weight of 269.06 g/mol.
The molecular framework of 261951-89-7 4 - Methoxy - 3 - (trifluoromethyl)benzyl bromide 4-(bromomethyl)-1-methoxy-2-(trifluoromethyl)benzene 4-(bromomethyl)-2-(trifluoromethyl)phenyl methyl ether 4-Bromomethyl-1-methoxy-2-trifluoromethyl-benzene benzene, 4-(bromomethyl)-1-methoxy-2-(trifluoromethyl)- (C9H8BrF3O) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
