Chemical Structure
Description
The occurrence of 3-bromopropyl trifluoromethanesulfonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-bromopropyl trifluoromethanesulfonate (CAS 103935-48-4), molecular formula C4H6BrF3O3S and molecular weight 271.05 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 3-bromopropyl trifluoromethanesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.05 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.
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.
