Chemical Structure

13478-28-9 CTK4B9422 Chromium iodide (CrI2)(6CI,7CI,8CI,9CI) CAS 13478-28-9 chemical structure

Description

The occurrence of 13478-28-9 CTK4B9422 Chromium iodide (CrI2)(6CI,7CI,8CI,9CI) is closely related to iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

13478-28-9 CTK4B9422 Chromium iodide (CrI2)(6CI,7CI,8CI,9CI) (CAS 13478-28-9) is a high-purity analytical reference standard with the molecular formula ICr and a molecular weight of 178.90 g/mol.

13478-28-9 CTK4B9422 Chromium iodide (CrI2)(6CI,7CI,8CI,9CI) (ICr) 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.

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.
