Chemical Structure
Description
4,4-Difluoro-2-(iodomethyl)tetrahydrofuran (CAS 2138271-33-5) is a high-purity analytical reference standard with the molecular formula C5H7F2IO and a molecular weight of 248.01 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/iodine substitution, 4,4-Difluoro-2-(iodomethyl)tetrahydrofuran is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.01 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
