Description

Calcium Dihydrogen Orthophosphate is a vital inorganic phosphate salt widely used as a source of calcium and bioavailable phosphorus. Its primary commercial value lies in its role as a highly effective nutritional supplement and functional additive in various industrial processes. This compound is essential for manufacturers in the food, feed, pharmaceutical, and fertilizer industries seeking a reliable, soluble source of essential minerals.

Application

• Food & Beverage Fortification: Used as a calcium and phosphorus supplement in baked goods, cereals, beverages, and nutritional products to enhance dietary mineral content.
• Animal Feed Premix: A critical ingredient in livestock, poultry, and aquaculture feed formulations to support bone development, growth, and metabolic functions.
• Pharmaceutical Excipient & Active: Employed in tablet formulations as a diluent or as a source of calcium and phosphate in mineral supplement medications.
• Fertilizer Industry: Acts as a water-soluble phosphorus source in specialty fertilizers and nutrient solutions for hydroponics and foliar feeding.
• Dental Products: Incorporated into toothpaste and dental care formulations for its remineralizing properties on tooth enamel.
• Leavening Agent: Functions as a slow-acting acid component in baking powders for controlled gas release during baking.

Quality Control

Our Calcium Dihydrogen Orthophosphate is manufactured under a stringent quality management system. Production batches are tested against rigorous specifications for purity, heavy metal content, and physical parameters to ensure compliance with relevant standards such as FCC (Food Chemicals Codex), USP (United States Pharmacopeia), and feed grade regulations. A Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and batch-to-batch consistency.

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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent caking and degradation due to atmospheric moisture.
