Chemical Structure
Description
The occurrence of 1,2-Dibromo-3-fluoro-4-iodo-benzene 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.
1,2-Dibromo-3-fluoro-4-iodo-benzene (CAS 881667-35-2) is a high-purity analytical reference standard with the molecular formula C6H2Br2FI and a molecular weight of 379.79 g/mol.
Owing to fluorine/bromine/iodine substitution, an aromatic ring system, 1,2-Dibromo-3-fluoro-4-iodo-benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.79 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.
CATO manufactures 1,2-Dibromo-3-fluoro-4-iodo-benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
