Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl(3S,4R)-4-(4-methoxyphenyl)pyrrolidine-3-carboxylate (CAS 1187933-27-2), molecular formula C13H17NO3 and molecular weight 235.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl(3S,4R)-4-(4-methoxyphenyl)pyrrolidine-3-carboxylate (C13H17NO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
