Chemical Structure
Description
1,8-Diiodo-3,3,4,4,5,5,6,6-octafluorooctane (CAS 2681-00-7), molecular formula C8H8F8I2 and molecular weight 509.95 g/mol, is a CATO reference standard with documented purity and traceability.
1,8-Diiodo-3,3,4,4,5,5,6,6-octafluorooctane (C8H8F8I2) contains fluorine/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.
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.
