1,2-Diiodoethane 624-73-7 D1025 Ethylene Diiodide Ethylene Iodide CAS 624-73-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,2-Diiodoethane 624-73-7 D1025 Ethylene Diiodide Ethylene Iodide (CAS 624-73-7) is a high-purity analytical reference standard with the molecular formula C2H4I2 and a molecular weight of 281.86 g/mol.

Owing to iodine substitution, 1,2-Diiodoethane 624-73-7 D1025 Ethylene Diiodide Ethylene Iodide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.86 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.

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.
