Chemical Structure
Description
The occurrence of 4-Bromo-2-thiophenecarbaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-2-thiophenecarbaldehyde (CAS 18791-75-8), molecular formula C5H7BrOS and molecular weight 195.08 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, 4-Bromo-2-thiophenecarbaldehyde is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.08 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
