Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,5-Dichloro-3-methoxypyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.02 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).
