Chemical Structure
Description
The occurrence of 3-Bromo-2-iodofuran is closely related to a hydroxyl group, an ether linkage, bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Bromo-2-iodofuran (CAS 72167-52-3) is a high-purity analytical reference standard with the molecular formula C4H2BrIO and a molecular weight of 272.87 g/mol.
Based on its molecular formula C4H2BrIO, 3-Bromo-2-iodofuran contains a hydroxyl group, an ether linkage, bromine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.87 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 3-Bromo-2-iodofuran 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.
