Chemical Structure
Description
5-Bromo-4-chloro-4,5,5-trifluoropent-2-enoic acid (C5H3BrClF3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-Bromo-4-chloro-4,5,5-trifluoropent-2-enoic acid (CAS 232602-80-1), molecular formula C5H3BrClF3O2 and molecular weight 267.43 g/mol, is a CATO reference standard with documented purity and traceability.
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-Bromo-4-chloro-4,5,5-trifluoropent-2-enoic acid 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.
