Anwendungen · 2 Einträge

BeschreibungDimethyl malonate is a diester derivative of malonic acid. It is a common reagent for organic synthesis used, for example, as a precursor for barbituric acid. It is also used in the malonic ester synthesis. It can be synthesized from dimethoxymethane and carbon monoxide.

VerwendenDimethyl malonate is a reagent used in organic synthesis. It acts as a precursor for the synthesis of mono-substituted and di-substituted acetic acid, barbiturates, vitamin B1 and vitamin B6. It is used in the pharmaceutical industry to prepare pharmaceuticals like chloroquine and butazolidin. It is involved in the synthesis of diastereomeric pure thienylpyridines by reacting with 1,3-diphenylprop-2-enyl acetate.
