Fumaric Acid is an unsaturated dicarboxylic acid naturally found in certain plants and fungi. Commercially, it is produced through the isomerisation of Maleic Acid and is widely used because of its high acidity, thermal stability and excellent chemical reactivity.
Its ability to function as an industrial intermediate makes it one of the most versatile organic acids available today for resin and chemical synthesis.
Fumaric Acid serves industries ranging from paper sizing and alkyd resins to unsaturated polyester, construction chemicals and specialty polymers.
| Property | Benefit to Manufacturers |
|---|---|
| High Purity | Consistent product quality |
| Strong Acidifying Effect | Efficient pH control & reaction reactivity |
| Low Hygroscopicity | Better storage stability |
| Excellent Thermal Stability | Suitable for high-temperature industrial processing |
| Unsaturated Structure | Useful for polymer and resin chemistry |
| Multi-Industry Applications | Industrial versatility across resins and coatings |
Fumaric Acid (CℤHℤOℤ) is the trans-isomer of butenedioic acid. Its molecular structure contains:
This combination gives it excellent chemical stability while allowing it to participate in polymerisation and esterification reactions.
Its dual functionality explains its extensive use in:
Because of its relatively low solubility in water compared to many organic acids, Fumaric Acid is often selected where gradual acid release or controlled reaction is desirable.
Commercial Fumaric Acid is manufactured through the conversion of Maleic Anhydride into Maleic Acid, followed by catalytic isomerisation into Fumaric Acid.

Unlike many commodity chemicals, Fumaric Acid pricing is influenced by both upstream petrochemical economics and downstream specialty demand. Key pricing factors include:
Because Fumaric Acid serves multiple industries, fluctuations in one sector are often balanced by demand from others, making it a relatively stable specialty chemical compared with single-industry intermediates. At Doshi Chemstar, we closely monitor these factors to help customers make informed procurement decisions.
If you use both Fumaric Acid and Gum Rosin, consider coordinated procurement to improve supply planning for Fortified Rosin production.
Fumaric Acid has a stronger acidifying effect than citric acid on an equal-weight basis, which allows manufacturers to achieve the desired acidity using lower quantities in many food applications.
