Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 168.57 g/mol gives (2S)-4,4-difluoropyrrolidine-2-carbonitrile;hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2S)-4,4-difluoropyrrolidine-2-carbonitrile;hydrochloride (CAS 869489-04-3) is a high-purity analytical reference standard with the molecular formula C5H6F2N2HCl and a molecular weight of 168.57 g/mol.
Owing to a nitrile group, fluorine/chlorine substitution, (2S)-4,4-difluoropyrrolidine-2-carbonitrile;hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.57 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.
