Pentaammonium triphosphate

Pentaammonium triphosphate (CAS 14693-67-5) is an ammonium salt of triphosphoric acid used across industrial and agricultural sectors for its chelating, buffering, and sequestration capabilities.

It binds metal ions and controls pH in process streams, making it a functional additive in formulations where phosphate chemistry is required for stabilization and performance.

In agriculture, it functions as a nitrogen and phosphorus source in liquid fertilizer blends, delivering both macronutrients in a single compound for efficient crop nutrition.

Water treatment operations use it to sequester calcium and magnesium ions, preventing scale formation in industrial cooling and process water systems to maintain equipment efficiency.

In textile and paper processing, it stabilizes bath chemistry and controls metal ion interference during dyeing, bleaching, and pulp treatment to ensure consistent product quality.

Food and nutrition applications leverage its buffering capacity to regulate pH in processed formulations where phosphate-based sequestrants are permitted under specific regulatory guidelines.

Pentaammonium triphosphate is typically supplied as a crystalline powder or in solution form depending on end-use requirements and the specific needs of the manufacturing process.

Technical grade is the most common specification for industrial applications, while food-grade material is available where regulatory compliance for phosphate sequestrants is required.
