Chemical Structure
Description
CATO supplies Ethyl 3-methyl-4,5-dioxo-1,2-diphenylpyrrolidine-3-carboxylate (CAS 5469-65-8), a certified reference material (molecular formula C20H19NO4, MW 337.37 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 3-methyl-4,5-dioxo-1,2-diphenylpyrrolidine-3-carboxylate (C20H19NO4) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Ethyl 3-methyl-4,5-dioxo-1,2-diphenylpyrrolidine-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
