Chemical Structure
Description
The occurrence of 3-bromo-1-benzothiophen-4-ol is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-bromo-1-benzothiophen-4-ol (CAS 34576-99-3), molecular formula C8H5BrOS and molecular weight 229.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 3-bromo-1-benzothiophen-4-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.09 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.
