Dipotassium phosphate

Dipotassium phosphate (CAS 7758-11-4 ), also known as potassium phosphate dibasic or DKP, is an inorganic potassium salt used across food, pharmaceutical, and industrial sectors.

It functions primarily as a buffering agent, pH regulator, and sequestrant in formulations where precise acidity control and mineral stabilization are critical for the final product.

In food and beverage manufacturing, DKP prevents protein precipitation and controls pH in dairy-based products, coffee creamers, and processed cheeses to ensure a consistent texture.

Pharmaceutical formulators use it as a buffering component in parenteral solutions, culture media, and tablet formulations requiring stable pH profiles during the manufacturing process.

Water treatment operations apply it to inhibit scale formation and sequester calcium and magnesium ions in distribution systems. It also serves as a nutrient source in fermentation media.

This chemical supports microbial growth in industrial bioprocessing and yeast-based production. Dipotassium phosphate is supplied as a white crystalline powder or anhydrous granules.

Recognized grades include food-grade ( FCC ), USP , and technical-grade, with food and pharma specifications being the most commonly traded materials in the global market.

Buyers sourcing for regulated applications typically require certificates of analysis aligned to USP or FCC monograph standards to ensure compliance with safety and quality protocols.
