Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 9-BROMO-4,5-DIHYDROBENZO[2,3]OXEPINO[4,5-D]THIAZOLE-2-CARBOXYLIC ACID is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.17 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.
