Chemical Structure
Description
The occurrence of Diethyl 2-(pent-4-en-1-yl)malonate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diethyl 2-(pent-4-en-1-yl)malonate (CAS 1906-96-3) is a high-purity analytical reference standard with the molecular formula C12H20O4 and a molecular weight of 228.28 g/mol.
Diethyl 2-(pent-4-en-1-yl)malonate (C12H20O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
