Zinc oxalate

Zinc oxalate (CAS 547-68-2, EC 208-934-2, formula C2O4Zn) is an inorganic zinc salt of oxalic acid, available commercially under trade names including Tegokat 634. It carries no E-code designation and is classified within the salts and minerals category. High-purity grades are supplied at 99.99%+ assay for demanding technical applications.

In mining and metals processing, zinc oxalate serves as a precursor in the controlled thermal decomposition route to zinc oxide, where its defined stoichiometry enables consistent particle morphology in the resulting oxide. In textile and leather processing, it functions as a catalyst or auxiliary agent in finishing reactions, facilitating chemical transformations at lower activation energies than alternative zinc sources.

Zinc oxalate is sourced in high-purity (99.99%+) powder form and is subject to REACH registration requirements for EU supply chains. Suppliers typically offer packaging in multi-kilogram quantities suited to industrial procurement volumes. Buyers should confirm grade specifications and documentation, including safety data sheets compliant with EU GHS/CLP regulation.
