Product Description

Itaconic acid 97-65-4

AI Product Description

*The following content is generated by AI and is for reference only.

Itaconic acid, chemically known as 2-methylenebutanedioic acid, is a versatile dicarboxylic acid with the molecular formula C5H6O4 and the CAS registry number 97-65-4. Historically derived from the fermentation of sugars by the fungus *Aspergillus terreus*, it has gained significant industrial attention as a sustainable platform chemical produced via bio-refining processes. Its unique structure features two carboxylic acid groups and a reactive methylene double bond, making it an exceptional monomer for polymer synthesis and a key intermediate in organic chemistry. In the polymer industry, itaconic acid is widely utilized to modify acrylic resins, polyesters, and alkyds. Its incorporation enhances water resistance, adhesion properties, and thermal stability while reducing production costs compared to traditional maleic anhydride derivatives. It plays a crucial role in manufacturing superabsorbent polymers used in hygiene products like diapers and agricultural hydrogels that retain soil moisture. Furthermore, its reactivity allows for the creation of biodegradable plastics, aligning with global sustainability goals to replace petroleum-based materials. Beyond polymerization, itaconic acid serves as a precursor for various high-value chemicals, including itaconate esters, itaconimide, and chelating agents used in water treatment and metal surface finishing. The compound exhibits strong chelating capabilities, effectively binding heavy metals, which makes it valuable in environmental remediation applications. In the pharmaceutical sector, it acts as a building block for synthesizing specific drugs and biological active compounds due to its metabolic relevance; indeed, it is naturally produced by human macrophages during immune responses, suggesting potential therapeutic applications in inflammation and infectious diseases. Global demand for itaconic acid is rising steadily, driven by the shift toward green chemistry and the need for renewable feedstocks. As fermentation technologies improve and production scales up, the cost competitiveness of bio-based itaconic acid continues to strengthen. Its dual nature as both a functional monomer and a chemical intermediate ensures its strategic importance across diverse sectors ranging from construction coatings and adhesives to advanced medical devices. Ultimately, itaconic acid represents a cornerstone of the emerging bio-economy, bridging the gap between agricultural resources and high-performance industrial materials.
