Chemical Structure
Description
The occurrence of 3-bromo-2-ethenylfuran is closely related to 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-2-ethenylfuran (CAS 1690740-99-8), molecular formula C6H5BrO and molecular weight 173.01 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-bromo-2-ethenylfuran (C6H5BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 173.01 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
