Chemical Structure
Description
1-[bis(fluoranyl)methyl]-4-bromanyl-2-fluoranyl-benzene 4-bromo-1-(difluoromethyl)-2-fluorobenzene 749932-17-0 A838300 (CAS 749932-17-0) is a high-purity analytical reference standard with the molecular formula C7H10BrF3 and a molecular weight of 231.05 g/mol.
The molecular framework of 1-[bis(fluoranyl)methyl]-4-bromanyl-2-fluoranyl-benzene 4-bromo-1-(difluoromethyl)-2-fluorobenzene 749932-17-0 A838300 (C7H10BrF3) is characterized by fluorine/bromine substitution. 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. 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.
