Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, chlorine/iodine substitution, an aromatic ring system, 6-Chloro-2-iodothieno[2,3-b]pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.53 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 6-Chloro-2-iodothieno[2,3-b]pyridine (CAS 1431869-34-9), a certified reference material (molecular formula C7H3ClINS, MW 295.53 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.
