Chemical Structure
Description
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.
(2S,4S)-4-(Fluoro-18F)pyrrolidine-2-carboxylic acid hydrochloride (CAS 2639893-65-3) is a high-purity analytical reference standard with the molecular formula C5H8[18F]NO2 HCl and a molecular weight of 169.58 g/mol.
The molecular framework of (2S,4S)-4-(Fluoro-18F)pyrrolidine-2-carboxylic acid hydrochloride (C5H8[18F]NO2 HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
