Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Benzyl 2-(3-ethoxy-3-oxopropanoyl)pyrrolidine-1-carboxylate (CAS 954220-90-7), molecular formula C17H21NO5 and molecular weight 319.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzyl 2-(3-ethoxy-3-oxopropanoyl)pyrrolidine-1-carboxylate (C17H21NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. 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.
