Chemical Structure
Description
2,2-Difluoro-1,3-dimethylimidazolidine (CAS 220405-40-3) is a high-purity analytical reference standard with the molecular formula C5H10F2N2 and a molecular weight of 136.14 g/mol.
Owing to fluorine substitution, 2,2-Difluoro-1,3-dimethylimidazolidine is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.14 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.
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.
