Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5-oxo-1-(4-propoxyphenyl)pyrrolidine-3-carboxylate.
CATO supplies Methyl 5-oxo-1-(4-propoxyphenyl)pyrrolidine-3-carboxylate (CAS 133748-34-2), a certified reference material (molecular formula C15H19NO4, MW 277.32 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 5-oxo-1-(4-propoxyphenyl)pyrrolidine-3-carboxylate (C15H19NO4) 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. 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.
