Description
1,2-Dibromo-1,1-difluoroethane (CAS 75-82-1), molecular formula C2H2Br2F2 and molecular weight 223.84 g/mol, is a CATO reference standard with documented purity and traceability.
1,2-Dibromo-1,1-difluoroethane (C2H2Br2F2) contains fluorine/bromine substitution. 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), 1,2-Dibromo-1,1-difluoroethane 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.
