Potassium tetroxalate dihydrate

Potassium tetroxalate dihydrate (CAS 6100-20-5) is an acidic potassium oxalate salt used industrially as a pH buffer, chelating agent, and cleaning active.

Where is Potassium tetroxalate dihydrate used?

• Mineral deposit removal: strongly acidic character in solution
• Metal ion and oxidation product removal across process industries
• Textile and leather processing: removes iron stains and rust from fabrics and hides without damaging fiber structure
• Industrial and household cleaning: dissolves limescale, metal oxides, and tannin-based stains from hard surfaces
• Paper manufacturing: supports bleaching and surface treatment where controlled acidity and metal ion sequestration are required
• Water treatment: reference-grade buffer standard and selective precipitation of calcium and heavy metal ions from process streams

Commercial specifications

• High-purity analytical grade for certified pH buffer standard
• Packaging from laboratory quantities to bulk industrial volumes
