Chemical Structure
Description
Owing to sulfur-containing functionality, bromine substitution, an aromatic ring system, 2-Bromobenzo[b]thiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 213.09 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.
