Chemical Structure
Description
1-IOdo-1h,1h,2h,2h-perfluoro(4,7,10,13,16-pentamethyl-5,8,11,14,17-pentaoxaeicosane) (C20H4F37IO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
1-IOdo-1h,1h,2h,2h-perfluoro(4,7,10,13,16-pentamethyl-5,8,11,14,17-pentaoxaeicosane) (CAS 1212369-20-4) is a high-purity analytical reference standard with the molecular formula C20H4F37IO5 and a molecular weight of 1154.09 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.
