Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-4-chloro-4,5,5-trifluoropentanoic acid (CAS 232602-79-8), molecular formula C5H5BrClF3O2 and molecular weight 269.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Bromo-4-chloro-4,5,5-trifluoropentanoic acid (C5H5BrClF3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 5-Bromo-4-chloro-4,5,5-trifluoropentanoic 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.
