Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-2-methyltetrahydro-2H-pyran is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.60 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.
