Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(2,3-Dibromopropyl)-2,3,5,6-tetrafluorobenzotrifluoride (CAS 1244856-10-7), molecular formula C10H5Br2F7 and molecular weight 417.94 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2,3-Dibromopropyl)-2,3,5,6-tetrafluorobenzotrifluoride (C10H5Br2F7) contains fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
