Chemical Structure
Description
CATO supplies 2-(3-Fluorophenyl)-5-(methoxycarbonyl)-1-methyl-3-pyrrolidinecarboxylic acid (CAS 1219159-23-5), a certified reference material (molecular formula C14H16FNO4, MW 281.28 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-(3-Fluorophenyl)-5-(methoxycarbonyl)-1-methyl-3-pyrrolidinecarboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.28 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).
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.
