Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-3-(Pyrrolidin-2-yl)-5-(trifluoromethyl)pyridine (CAS 1213536-99-2) is a high-purity analytical reference standard with the molecular formula C10H11F3N2 and a molecular weight of 216.20 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, (S)-3-(Pyrrolidin-2-yl)-5-(trifluoromethyl)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
