High-purity chemical compounds for global processing and manufacturing
Maleic Anhydride (CAS No. 108-31-6) is a vital organic intermediate widely utilized in industrial syntheses. In commercial chemistry, scientific reference via the PubChem database (CID 7922) provides the universal standard for verifying molecular structure, toxicological profiles, physical properties, and safety classifications.
As a premium Chinese chemical manufacturer, Shandong Pulisi ensures that all Maleic Anhydride batches strictly meet these established global chemical characteristics. The compound is synthesized primarily through the controlled catalytic oxidation of benzene or n-butane, yielding a highly reactive monomer ideal for polymerization and esterification.
"By integrating modern chromatography with high-purity crystallization methods, our Maleic Anhydride delivers structural integrity that matches the highest PubChem databases parameters, ensuring seamless reaction kinetics in downstream manufacturing."
