Dimethyl malonate

Dimethyl malonate (CAS 108-59-8, EC 203-597-8) is a diester of malonic acid with methanol, also referenced under the names malonic acid dimethyl ester and dicarbmethoxymethane. It carries no assigned E-code and is commercially identified under NSC 620046. It belongs to the malonate ester family within the flavors and fragrances chemical category.

In food and beverage formulation, dimethyl malonate functions as a flavorant by contributing mild fruity and apple-like notes at low use concentrations. In personal care applications, it serves as a fragrance ingredient where its ester structure provides controlled volatility and blending compatibility with other aroma chemicals. Its reactivity as a methylene donor also makes it a building block in flavor synthesis routes.

Dimethyl malonate is supplied as a liquid and is available in food-grade quality meeting FCC specifications. It falls under REACH regulation and is classified under HS code 29171910 for customs purposes. Procurement in Europe typically covers drum and IBC formats from registered suppliers holding full safety and compliance documentation.
