Chemical Structure
Description
Diethyl 2-ethyl-2-(4-nitrophenyl)malonate (CAS 83397-44-8), molecular formula C15H19NO6 and molecular weight 309.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diethyl 2-ethyl-2-(4-nitrophenyl)malonate (C15H19NO6) 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.
CATO manufactures Diethyl 2-ethyl-2-(4-nitrophenyl)malonate 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.
