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.
5-Bromo-4-(chlorosulfonyl)furan-2-carboxylic acid (CAS 1016505-47-7), molecular formula C5H2BrClO5S and molecular weight 289.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, a sulfone group, chlorine/bromine substitution, 5-Bromo-4-(chlorosulfonyl)furan-2-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
