Malonic acid is acts as a building block in organic synthesis. It is also useful as a precursor for polyesters and alkyd resins, which is used in coating applications, thereby protecting against UV light, corrosion and oxidation. It acts as a cross linker in the coating industry and surgical adhesive. It finds application in the production of specialty chemicals, flavors and fragrances, polymer cross linkers and pharmaceuticals.

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.

Aplicaciones
El ácido malónico se utiliza como compuesto básico en la síntesis orgánica. También es útil como precursor para poliésteres y resinas alquídicas, que se utiliza en aplicaciones de revestimiento, lo que protege contra la luz UV, la corrosión y la oxidación. Actúa como entrecruzador en la industria de los revestimientos y en los adhesivos quirúrgicos. Se aplica en la producción de productos químicos especiales, sabores y fragancias, entrecruzadores de polímeros y productos farmacéuticos.

Solubilidad
Soluble en agua fría.

Notas
Incompatible con bases, agentes oxidantes y agentes reductores.
