Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,4-Bis(bromomethyl)-2,5-dihydrothiophene 1,1-dioxide (CAS 18214-57-8), molecular formula C6H8Br2O2S and molecular weight 304.00 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, bromine substitution, 3,4-Bis(bromomethyl)-2,5-dihydrothiophene 1,1-dioxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.00 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.
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.
