Chemical Structure
Description
Owing to sulfur-containing functionality, fluorine/bromine substitution, 5-Bromo-2-(bromomethyl)-3-fluorothiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.95 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.
CATO supplies 5-Bromo-2-(bromomethyl)-3-fluorothiophene (CAS 2762116-95-8), a certified reference material (molecular formula C5H3Br2FS, MW 273.95 g/mol) for analytical method development and quality control.
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.
