Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,2-Difluoro-3,4-dihydro-2H-pyrrol-5-amine (CAS 802002-40-0) is a high-purity analytical reference standard with the molecular formula C4H6F2N2 and a molecular weight of 120.10 g/mol.
2,2-Difluoro-3,4-dihydro-2H-pyrrol-5-amine (C4H6F2N2) contains a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
