Chemical Structure
Description
1-Bromo-4-iodobutane (CAS 89044-65-5) is a high-purity analytical reference standard with the molecular formula C4H8BrI and a molecular weight of 262.91 g/mol.
1-Bromo-4-iodobutane (C4H8BrI) contains bromine/iodine 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.
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.
