Chemical Structure
Description
CATO supplies 2,3-Dihydro-3-(iodomethyl)-benzofuran (CAS 78739-83-0), a certified reference material (molecular formula C9H9IO, MW 260.07 g/mol) for analytical method development and quality control.
2,3-Dihydro-3-(iodomethyl)-benzofuran (C9H9IO) contains a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
