Description

CAS: 87-13-8 | C10H16O5 | 216.233 g/mol

Diethyl ethoxymethylenemalonate is used for synthesis of pyrido[3,2-e]pyrimido[1,2-c]pyrimidines. Initially, it was used to monitor lysine decarboxylase activity. It is useful in the determination of amino acids by precolumn derivatization by using reversed-phase high-performance liquid chromatography (HPLC). It plays an important role in the Gould-Jacobs reaction to prepare quinolines. For example, anile reacts with this reagent to give 4-hydroxyquinoline. It acts as an intermediate in the production of flumequine, which is a fluoroquinolone antibiotic.

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. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
