Chemical Structure
Description
Owing to sulfur-containing functionality, bromine/iodine substitution, an aromatic ring system, 3-Bromo-6-iodothieno[3,2-b]thiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.02 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).
CATO supplies 3-Bromo-6-iodothieno[3,2-b]thiophene (CAS 1394840-27-7), a certified reference material (molecular formula C6H2BrIS2, MW 345.02 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.
