Chemical Structure
Description
4-Iodo-2,2-dimethyltetrahydro-2H-pyran (C7H13IO) contains a hydroxyl group, an ether linkage, iodine substitution. 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.
4-Iodo-2,2-dimethyltetrahydro-2H-pyran (CAS 882687-80-1) is a high-purity analytical reference standard with the molecular formula C7H13IO and a molecular weight of 240.08 g/mol.
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.
