Description

Pentaammonium Triphosphate is an inorganic ammonium salt of triphosphoric acid, recognized by the CAS registry number 14693-67-5. This compound serves as a versatile source of both ammonium and condensed phosphate ions, making it valuable for applications requiring controlled nutrient release or sequestration. It is particularly relevant for industrial manufacturers and formulators in sectors such as water treatment, specialty cleaning, and certain niche agricultural products. Its utility is defined by its specific chemical reactivity and ionic composition.

Application

• Water Treatment: Acts as a scale and corrosion inhibitor in industrial cooling and boiler water systems.
• Specialty Detergents & Cleaners: Functions as a sequestrant and builder in formulations for industrial and institutional cleaning.
• Flame Retardancy: Used as a component in certain intumescent coatings and fire-resistant materials.
• Ceramics & Glass: Serves as a dispersing agent and flux in the production of specialty ceramics and glass.
• Textile Processing: Employed as a softening agent and auxiliary in specific dyeing and finishing processes.
• Laboratory Reagent: Utilized in research and analytical chemistry as a source of triphosphate ions.
• Metal Surface Treatment: Applied in formulations for metal cleaning, phosphating, and surface passivation.
• Niche Agricultural Additives: Incorporated into certain fertilizer blends or soil amendment products for controlled nutrient delivery.

Quality Control

Our Pentaammonium Triphosphate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, phosphate content, ammonium content, and impurity levels are provided with every shipment. We adhere to relevant industrial quality standards and can support compliance documentation as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture and caking. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from incompatible materials.
