Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Iodo-2,3-dimethylbenzo[b]thiophene.
CATO supplies 5-Iodo-2,3-dimethylbenzo[b]thiophene (CAS 1936284-05-7), a certified reference material (molecular formula C10H9IS, MW 288.15 g/mol) for analytical method development and quality control.
5-Iodo-2,3-dimethylbenzo[b]thiophene (C10H9IS) contains sulfur-containing functionality, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
