Product Overview

Potassium Oxalate Monohydrate 99% Extra Pure (CAS No. 6487-48-5) is the monohydrate of the dipotassium salt of oxalic acid. The oxalate dianion is a bidentate oxygen-donor ligand capable of coordinating metal ions and forming sparingly soluble oxalates with selected cations, notably calcium. It also participates in redox and coordination reactions characteristic of oxalate chemistry. The monohydrate identity is part of the exact catalogue form.

The Extra Pure grade is suited to general coordination chemistry, preparation of metal oxalates, precipitation studies and routine laboratory work requiring a soluble potassium oxalate reagent.

Typical Applications

• Source of oxalate ions in inorganic and coordination chemistry.
• Preparation of metal oxalate complexes and coordination materials.
• Precipitation studies involving calcium oxalate and other sparingly soluble oxalates.
• Preparation of oxalate-containing laboratory reagent solutions.
• Metal-ion complexation and speciation investigations.
• General synthesis and materials research involving oxalate ligands.

Common Synonyms

• Dipotassium oxalate monohydrate
• Oxalic acid dipotassium salt monohydrate
• Dipotassium ethanedioate monohydrate
• Potassium oxalate hydrate
• Dipotassium oxalate hydrate

Storage Conditions

Keep tightly closed and protect from uncontrolled moisture exchange so that the defined monohydrate form and weighed composition are maintained. Prevent contamination by metal salts that can form sparingly soluble oxalates and thereby alter reagent purity or solution behaviour.
