Chemical Structure
Description
Owing to a nitrile group, fluorine substitution, 2-(3,3-Difluorocyclopentyl)acetonitrile is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.15 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.
2-(3,3-Difluorocyclopentyl)acetonitrile (CAS 1701764-04-6) is a high-purity analytical reference standard with the molecular formula C7H9F2N and a molecular weight of 145.15 g/mol.
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.
