Chemical Structure
Description
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.
1,2-Dichloro-4-iodo-1,1,2-trifluorobutane (CAS 679-69-6), molecular formula C4H4Cl2F3I and molecular weight 306.88 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/chlorine/iodine substitution, 1,2-Dichloro-4-iodo-1,1,2-trifluorobutane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.88 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
