Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(1-(4-Ethoxyphenyl)-5-oxopyrrolidin-3-yl)-3-((tetrahydrofuran-2-yl)methyl)urea (CAS 894013-32-2) is a high-purity analytical reference standard with the molecular formula C18H25N3O4 and a molecular weight of 347.41 g/mol.
The molecular framework of 1-(1-(4-Ethoxyphenyl)-5-oxopyrrolidin-3-yl)-3-((tetrahydrofuran-2-yl)methyl)urea (C18H25N3O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 1-(1-(4-Ethoxyphenyl)-5-oxopyrrolidin-3-yl)-3-((tetrahydrofuran-2-yl)methyl)urea 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.
