Chemical Structure
Description
The occurrence of 1,3-Dibromo-2-fluoro-4-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.
1,3-Dibromo-2-fluoro-4-iodobenzene (CAS 1804417-87-5), molecular formula C6H2Br2FI and molecular weight 379.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3-Dibromo-2-fluoro-4-iodobenzene (C6H2Br2FI) is characterized by fluorine/bromine/iodine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
