Pentaammonium triphosphate

Pentaammonium triphosphate (CAS 14693-67-5) is an ammonium salt of triphosphoric acid with chelating, buffering and sequestration capabilities.

Where is Pentaammonium triphosphate used?

• Agriculture: nitrogen and phosphorus source in liquid fertilizer blends
• Water treatment: sequesters calcium and magnesium ions, preventing scale in cooling and process water
• Textile and paper processing: stabilizes bath chemistry and controls metal ion interference in dyeing, bleaching and pulp treatment
• Food and nutrition: buffering agent regulating pH where phosphate-based sequestrants are permitted
• It binds metal ions and controls pH in process streams.
