The occurrence of Ethyl 5-(2-(2-oxo-2-(pyrrolidin-1-yl)acetyl)-1H-pyrrol-1-yl)-1-phenyl-1H-pyrazole-4-carboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 5-(2-(2-oxo-2-(pyrrolidin-1-yl)acetyl)-1H-pyrrol-1-yl)-1-phenyl-1H-pyrazole-4-carboxylate (CAS 477709-26-5) is a high-purity analytical reference standard with the molecular formula C22H22N4O4 and a molecular weight of 406.43 g/mol.
The molecular framework of Ethyl 5-(2-(2-oxo-2-(pyrrolidin-1-yl)acetyl)-1H-pyrrol-1-yl)-1-phenyl-1H-pyrazole-4-carboxylate (C22H22N4O4) 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.
