Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 240.30 g/mol gives Diethyl 2,2-diallylmalonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diethyl 2,2-diallylmalonate (CAS 3195-24-2) is a high-purity analytical reference standard with the molecular formula C13H20O4 and a molecular weight of 240.30 g/mol.
The molecular framework of Diethyl 2,2-diallylmalonate (C13H20O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Diethyl 2,2-diallylmalonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
