Chemical Structure
Description
The occurrence of 1-Bromo-3,4-difluoro-5-iodobenzene is closely related to fluorine/bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-3,4-difluoro-5-iodobenzene (CAS 1807026-65-8) is a high-purity analytical reference standard with the molecular formula C6H2BrF2I and a molecular weight of 318.89 g/mol.
Owing to fluorine/bromine/iodine substitution, an aromatic ring system, 1-Bromo-3,4-difluoro-5-iodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
