Description

Ethyl hydrogen malonate (CAS No. 1071-46-1), also known as monoethyl malonate or 3-ethoxy-3-oxopropanoic acid, is a high-purity organic compound with the molecular formula C₅H₈O₄. This versatile ester-carboxylic acid hybrid is widely utilized in organic synthesis, pharmaceutical research, and specialty chemical manufacturing. The compound presents as a clear to slightly yellow liquid under standard conditions, offering excellent solubility in common organic solvents such as ethanol, diethyl ether, and acetone.

With a molecular weight of 132.11 g/mol, ethyl hydrogen malonate serves as a valuable building block for malonic acid derivatives and other complex molecular architectures. Its bifunctional nature (containing both ester and carboxylic acid groups) makes it particularly useful for condensation reactions and as a precursor in heterocyclic chemistry. Our product is rigorously tested to ensure optimal purity (>98%) and consistency, meeting the exacting standards of research laboratories and industrial applications.

Key identifiers include EINECS 213-992-7 and DTXSID10147915. Proper storage recommendations include maintaining the product in a tightly sealed container at 2-8??C, protected from moisture and light to ensure long-term stability.

Application

Ethyl hydrogen malonate is primarily employed as a synthetic intermediate in pharmaceutical research, particularly in the preparation of barbiturates and other heterocyclic compounds. The compound serves as a versatile precursor for malonate esters and diethyl malonate derivatives through straightforward chemical modifications. In material science, it finds application as a monomer or cross-linking agent for specialty polymer synthesis. Researchers also utilize this chemical in organic transformations where its dual functionality enables selective reactions at either the ester or carboxylic acid group.
