Chemical Structure
Description
1,5-Difluoro-3-iodo-2-methoxybenzene (CAS 41860-66-6) is a high-purity analytical reference standard with the molecular formula C7H5F2IO and a molecular weight of 270.02 g/mol.
Structurally, 1,5-Difluoro-3-iodo-2-methoxybenzene (C7H5F2IO) contains a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 270.02 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
