Description

Tri-Magnesium Phosphate Octahydrate is a high-purity inorganic salt essential for applications requiring a controlled-release source of magnesium and phosphate ions. Its consistent quality and stability make it a critical functional ingredient for manufacturers prioritizing product uniformity and regulatory compliance. This compound is primarily sought by producers in the food & beverage, pharmaceutical, and specialty chemical industries.

Application

• Food Additive & Nutrient Fortification: Used as an anti-caking agent, pH regulator, and mineral supplement in powdered food products, beverages, and dietary supplements.
• Pharmaceutical Excipient: Serves as a binder, diluent, or source of magnesium in tablet and capsule formulations.
• Ceramics & Glass Manufacturing: Acts as a flux and stabilizer in the production of specialty glasses and ceramic glazes.
• Precursor for Advanced Materials: Used in the synthesis of magnesium phosphate-based catalysts, ceramics, and flame-retardant materials.
• Laboratory Reagent: Employed in analytical chemistry and biochemical research as a buffer component or standard.
• Animal Feed Supplement: Provides essential magnesium and phosphorus in mineral premixes for livestock and poultry nutrition.

Quality Control

Our Tri-Magnesium Phosphate Octahydrate is manufactured under a strict quality management system. Each batch is tested to ensure it meets relevant specifications for target applications, including potential compliance with FCC (Food Chemicals Codex) and USP/NF standards. Comprehensive Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture and caking.
