Chemical Structure
Description
2,3-Dibromo-1,1,1-trifluoropropane (CAS 431-21-0) is a high-purity analytical reference standard with the molecular formula C3H3Br2F3 and a molecular weight of 255.86 g/mol.
2,3-Dibromo-1,1,1-trifluoropropane (C3H3Br2F3) 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), 2,3-Dibromo-1,1,1-trifluoropropane 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.
