The occurrence of Methyldiiodoarsine is closely related to iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyldiiodoarsine (CAS 7207-97-8), a certified reference material (molecular formula ICH3As, MW 216.86 g/mol) for analytical method development and quality control.
Owing to iodine substitution, Methyldiiodoarsine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.86 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.
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.
