Chemical Structure
Description
The occurrence of 2-(Difluoromethyl)-5-iodofuran is closely related to a hydroxyl group, an ether linkage, fluorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(Difluoromethyl)-5-iodofuran (CAS 1401670-89-0) is a high-purity analytical reference standard with the molecular formula C5H3F2IO and a molecular weight of 243.98 g/mol.
Structurally, 2-(Difluoromethyl)-5-iodofuran (C5H3F2IO) contains a hydroxyl group, an ether linkage, fluorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 243.98 g/mol, it falls into the medium-molecular-weight range. 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.
