Chemical Structure
Description
The occurrence of 2-Bromo-3,5-diiodopyridine is closely related to a nitrile group, bromine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-3,5-diiodopyridine (CAS 885952-14-7) is a high-purity analytical reference standard with the molecular formula C5H2BrI2N and a molecular weight of 409.79 g/mol.
Owing to a nitrile group, bromine/iodine substitution, 2-Bromo-3,5-diiodopyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 409.79 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.
