Potassium hydrogen oxalate

Potassium hydrogen oxalate (CAS 127-95-7), also known as potassium binoxalate, is an acidic potassium salt used industrially as a pH buffer, chelating agent, and metal ion sequestrant.

Where is Potassium hydrogen oxalate used?

• Textile and leather processing: mordant and pH-regulating agent
• Dyeing and tanning: improves dye uptake consistency
• Mining and metals: selective precipitation or complexing of metal ions during ore processing and surface treatment
• Paper manufacturing: supports bleaching and pulp treatment where controlled acidity is critical to fiber integrity
• Pharmaceutical and analytical procurement: reagent-grade material
• It also serves as an intermediate in synthesis workflows requiring precise oxalate chemistry.

Commercial specifications

• Packaging from small drums to bulk quantities
