Chemical Structure
Description
The occurrence of germanium iodide is closely related to iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
germanium iodide (CAS 13573-08-5), molecular formula GeI2 and molecular weight 326.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of germanium iodide (GeI2) is characterized by iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
