Chemical Structure
Description
5-(4-Bromo-3-chlorophenyl)-2-furaldehyde (C11H6BrClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
5-(4-Bromo-3-chlorophenyl)-2-furaldehyde (CAS 428465-30-9) is a high-purity analytical reference standard with the molecular formula C11H6BrClO2 and a molecular weight of 285.52 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-(4-Bromo-3-chlorophenyl)-2-furaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
