Z422836G9D 7790-87-6 Cerous iodide Cerium triiodide EINECS 232-228-3 UNII-Z422836G9D (CAS 7790-87-6) is a high-purity analytical reference standard with the molecular formula CeI3 and a molecular weight of 520.83 g/mol.
Z422836G9D 7790-87-6 Cerous iodide Cerium triiodide EINECS 232-228-3 UNII-Z422836G9D (CeI3) contains 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.
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.
