Compared with other compounds in its class, the molecular weight of 269.85 g/mol gives Diiodomethane-d2 (stabilized with copper) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diiodomethane-d2 (stabilized with copper) (CAS 15729-58-5), molecular formula CD2I2 and molecular weight 269.85 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, iodine substitution, Diiodomethane-d2 (stabilized with copper) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.85 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.
