Ethyl hydrogen malonate, 96%, Thermo Scientific Chemicals

Description

Ethyl hydrogen malonate is used as a reactant for the preparation of tetramic acids through Dieckmann ring closure and organocatalytic decarboxylative Doebner-Knoevenagel reactions. It is involved in the acylation reactions and Knoevenagel condensation with aldehydes. It is also used in the preparation of gamma-lactones from olefins by intermolecular carbolactonization in presence of Mn(III) acetate as a catalyst.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
