Iridium(IV) iodide CAS 7790-45-6

Description

Compared with other compounds in its class, the molecular weight of 699.83 g/mol gives Iridium(IV) iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Iridium(IV) iodide (CAS 7790-45-6), molecular formula I4Ir and molecular weight 699.83 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula I4Ir, Iridium(IV) iodide contains iodine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 699.83 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
