Chemical Structure
Description
5-Bromo-2-(bromomethyl)-1-chloro-3-fluorobenzene (CAS 1823959-60-9), molecular formula C7H4Br2ClF and molecular weight 302.37 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-(bromomethyl)-1-chloro-3-fluorobenzene (C7H4Br2ClF) contains fluorine/chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
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-2-(bromomethyl)-1-chloro-3-fluorobenzene 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.
