Calcium sodium phosphate

Calcium sodium phosphate (CAS 13780-17-1), also known commercially as Rhenanite, is an inorganic phosphate salt used as a pH buffer and mineral source across food, pharmaceutical, and agricultural applications.

It provides controlled phosphate delivery in systems where both calcium and sodium cation balance is relevant to formulation performance. In food manufacturing, it functions as a buffering and leavening agent.

This compound is utilized in baked goods, processed cheeses, and dry-mix products where pH stability directly affects texture and shelf life. Pharmaceutical formulators use it as a mineral excipient and pH-adjusting agent.

It is commonly found in tablet and powder formulations requiring controlled calcium and phosphate content. In animal feed, it serves as a bioavailable phosphorus and calcium supplement for livestock and poultry.

The material supports bone development and metabolic function in various diets. It is also evaluated in fertilizer blends where slow-release phosphate delivery to soil is a primary formulation objective.

Calcium sodium phosphate is supplied as a white crystalline powder or fine granules depending on the intended application. Food-grade and feed-grade specifications are the most commercially prevalent.

Technical-grade material is also available for agricultural and industrial use. Buyers should confirm particle size distribution and purity grade when sourcing, as these parameters vary between suppliers.

These specific factors directly affect dissolution behavior in end formulations. Ensuring the material meets necessary quality standards is essential for maintaining consistency in large-scale chemical production.
