Chemical Structure
Description
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.
Bis(4-bromo-3,3,4,4-tetrafluorobutyl) carbonate (CAS 1923267-07-5) is a high-purity analytical reference standard with the molecular formula C9H8Br2F8O3 and a molecular weight of 475.95 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, Bis(4-bromo-3,3,4,4-tetrafluorobutyl) carbonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 475.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
