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.
(Diiodomethyl)cyclohexane (CAS 65826-85-9) is a high-purity analytical reference standard with the molecular formula C7H12I2 and a molecular weight of 349.98 g/mol.
Owing to iodine substitution, (Diiodomethyl)cyclohexane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.98 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.
