Malonic Acid (CAS 141-82-2) is a highly reactive dicarboxylic acid characterized by its active methylene group, establishing it as a fundamental intermediate in complex organic synthesis. This Propanedioic Acid is extensively utilized in the manufacturing of pharmaceutical active ingredients and agrochemical precursors through condensation reactions, where its structural versatility enables the formation of diverse heterocyclic compounds. In industrial surface treatments and electronics, Methane Dicarboxylic Acid functions as a precise acidity regulator and cross-linking agent within high-performance coating systems and soldering fluxes. To support these industrial applications, we offer consistent bulk supply options tailored for continuous manufacturing streams. Our logistic operations ensure competitive factory pricing for global partners, accompanied by full regulatory documentation including MSDS, TDS, COA. Furthermore, we maintain the capability to develop customized specifications regarding purity levels and packaging to meet rigorous production standards.

Product Description
Malonic acid
Product name and properties: malonic acid, content 99%, white powder small crystals.
1. Mainly used in adhesives, resin additives, electroplating polishes, welding and melting additives, etc.
4. Malonic acid and its esters are mainly used in fragrances, adhesives, resin additives, complexing agents, electroplating polishing agents, thermal welding and melting additives, etc. Malonic acid is used as an aluminum surface treatment agent, and there is no pollution problem because only water and carbon dioxide are generated when decomposed by heating. In this regard, it has great advantages compared with formic acid and other acid treatment agents used in the past.
5. Malonic acid is used as an additive substance for electroless plating, and also as an electroplating polishing agent.
Packaging: Lined with a two-layer plastic bag, 25 kg.
Storage: Sealed storage in a dry, low-temperature and well-ventilated place.
FAQ - Technical & Supply Chain
-
Q:
Is malonic acid different from malonate salts or esters?
A: Yes. Malonic acid refers specifically to the free acid form, while malonate salts and esters are distinct derivatives with different properties and CAS numbers. -
Q:
What is the primary technical function of Malonic Acid in the formulation of electronics soldering fluxes?
A: Malonic Acid acts as a highly effective activator in non-corrosive flux systems. Its acidity allows it to dissolve metal oxides from copper or tin surfaces at soldering temperatures, ensuring proper wetting and adhesion. Unlike stronger mineral acids, it decomposes or volatilizes cleanly without leaving conductive residues that could cause short circuits in high-density circuit boards.
