Chemical Structure
Description
The occurrence of 4-Bromo-3,5-diiodo-2,6-dimethylpyridine is closely related to a nitrile group, bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-3,5-diiodo-2,6-dimethylpyridine (CAS 98273-60-0) is a high-purity analytical reference standard with the molecular formula C7H6BrI2N and a molecular weight of 437.84 g/mol.
Owing to a nitrile group, bromine/iodine substitution, an aromatic ring system, 4-Bromo-3,5-diiodo-2,6-dimethylpyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
