Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2,4-Dichloro-3,7,7-trimethyl-7,8-dihydro-5H-pyrano[4,3-b]pyridine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 246.13 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.
