Description

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. It is commercially available as a stable, water-soluble solid suited for controlled-acidity processing environments. In textile and leather processing, it functions as a mordant and pH-regulating agent. During dyeing and tanning operations, it improves dye uptake consistency. The mining and metals sector uses it to selectively precipitate or complex metal ions during ore processing and surface treatment of metals. In paper manufacturing, it supports bleaching and pulp treatment processes where controlled acidity is critical to fiber integrity. Pharmaceutical manufacturers source it as a reagent-grade material for analytical applications. It also serves as an intermediate in synthesis workflows requiring precise oxalate chemistry. Potassium hydrogen oxalate is supplied as a white crystalline powder or granule for industrial use. Technical grade is the standard commercial form, with reagent and analytical grades available for laboratory and pharmaceutical procurement. Packaging typically ranges from small drums to bulk quantities. Contact us for supply of Potassium hydrogen oxalate Request Quote
