Chemical Structure
Description
The occurrence of 1,2-Dibromo-3,3,4,4,4-pentafluorobut-1-ene is closely related to fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2-Dibromo-3,3,4,4,4-pentafluorobut-1-ene (CAS 1824865-30-6) is a high-purity analytical reference standard with the molecular formula C4HBr2F5 and a molecular weight of 303.85 g/mol.
The molecular framework of 1,2-Dibromo-3,3,4,4,4-pentafluorobut-1-ene (C4HBr2F5) is characterized by fluorine/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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
