Description
7790-29-6 18CYW0VL2X Rubidium iodide Rubidium iodide (RbI) EINECS 232-198-1 Rubidium-iodid Rubidium jodatum UNII-18CYW0VL2X (CAS 7790-29-6), molecular formula IRb and molecular weight 212.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula IRb, 7790-29-6 18CYW0VL2X Rubidium iodide Rubidium iodide (RbI) EINECS 232-198-1 Rubidium-iodid Rubidium jodatum UNII-18CYW0VL2X contains iodine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 212.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
