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. Its strongly acidic character in solution makes it effective for removing mineral deposits.

This chemical is highly efficient at removing metal ions and oxidation products across multiple process industries. In textile and leather processing, it removes iron stains and rust from fabrics and hides without damaging fiber structure.

Industrial and household cleaning formulations use it to dissolve limescale, metal oxides, and tannin-based stains from hard surfaces. It provides a reliable solution for maintaining equipment and surface integrity in harsh environments.

In paper manufacturing, it supports bleaching and surface treatment steps where controlled acidity and metal ion sequestration are both required. This ensures high-quality output and consistent results during the production cycle.

Water treatment operations apply it as a reference-grade buffer standard and for selective precipitation of calcium and heavy metal ions from process streams. This versatility makes it a staple in environmental management.

Potassium tetroxalate dihydrate is supplied as a white crystalline powder or granular solid. It is available in technical grade for industrial cleaning and process applications, ensuring cost-effective performance for large-scale use.

It is also available in high-purity analytical grade for use as a certified pH buffer standard. Packaging typically ranges from laboratory quantities to bulk industrial volumes depending on the specific grade and application requirements.
