Hazards Summary
Causes no skin irritation and mild to moderate eye irritation in rabbits; No adverse effects observed in oral or dermal lethal-dose studies of rats (LD50s > 2,000 mg/kg); Reversible hepatocellular hypertrophy (considered indicative of liver metabolism rather than systemic toxicity) observed in an oral repeated-dose study of rats at the highest tested dose (1,000 mg/kg/day); No evidence of reproductive toxicity, developmental toxicity, or mutagenicity; [OECD SIDS: Malonic Acid Diesters - 2005] May cause irritation; [Alfa Aesar MSDS]

Applications
DescriptionDimethyl 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.
UsesIt is used in fragrances and some artificial flavorings .
UsesDimethyl 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.
General DescriptionDimethyl malonate undergoes enantioselective palladium-catalyzed allylic substitution reaction with 1,3-diphenylprop-2-enyl acetate to yield diastereomeric pure thienylpyridines.
