Chemical Structure
Description
Owing to iodine substitution, 13569-75-0 Chromium iodide (CrI3) Chromium triiodide Chromium iodide EINECS 236-991-3 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
13569-75-0 Chromium iodide (CrI3) Chromium triiodide Chromium iodide EINECS 236-991-3 (CAS 13569-75-0), molecular formula CrI3 and molecular weight 432.71 g/mol, is a CATO reference standard with documented purity and traceability.
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.
