Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Diethyl 2,2-bis(2-oxo-2-phenylethyl)malonate (CAS 300677-33-2) is a high-purity analytical reference standard with the molecular formula C23H24O6 and a molecular weight of 396.43 g/mol.
The molecular framework of Diethyl 2,2-bis(2-oxo-2-phenylethyl)malonate (C23H24O6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
CATO manufactures Diethyl 2,2-bis(2-oxo-2-phenylethyl)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.
