Food Grade Calcium Hydrogenphosphate Dihydrate CaHPO4.2H2O CAS 7789-77-7 Dicalcium Phosphate Dihydrate

 

Description:
Calcium Hydrogenphosphate Dihydrate is an inorganic compound that exists as a white, crystalline powder or granules. It is composed of calcium cations (Ca2+) and hydrogenphosphate anions (HPO42-). The dihydrate form indicates that it contains two molecules of water (H2O) per unit of calcium hydrogenphosphate.

Specification:
The specifications of Calcium Hydrogenphosphate Dihydrate can vary depending on the specific grade and application. Here are some general specifications:

• Chemical formula: CaHPO4·2H2O
• Molecular weight: 172.09 g/mol
• Appearance: White crystalline powder or granules
• Solubility: Soluble in acids, sparingly soluble in water
• Assay: Typically, not less than 98% (on a dried basis)
• Loss on drying: Usually, not more than 8% (dihydrate content)
• pH (1% solution): Generally, between 6.0 and 8.0
• Calcium content (Ca): Typically, not less than 22.0% (on a dried basis)

Application:

1. Food and beverage industry: Calcium Hydrogenphosphate Dihydrate is used as a calcium supplement and a buffering agent in the food and beverage industry. It can be added to various products, including baked goods, dairy products, and nutritional supplements, to fortify them with calcium and adjust the pH.

2. Pharmaceutical industry: Calcium Hydrogenphosphate Dihydrate is commonly used as an excipient in pharmaceutical formulations. It can act as a filler or diluent in tablets, capsules, and powders, providing bulk and aiding in tablet formation.

3. Animal feed industry: Calcium Hydrogenphosphate Dihydrate is utilized in animal feed formulations as a source of calcium and phosphorus. It is an important mineral supplement for livestock and poultry, contributing to skeletal development, egg production, and overall animal health.

4. Fertilizer industry: Calcium Hydrogenphosphate Dihydrate is sometimes used as a source of calcium and phosphorus in fertilizers, particularly in agricultural applications where these nutrients are essential for plant growth and development.

Features:

1. Calcium and phosphorus source: Calcium Hydrogenphosphate Dihydrate provides a source of both calcium and phosphorus, which are important minerals for various biological processes, including bone formation, nerve function, and enzyme activity.

2. Solubility and bioavailability: The compound is sparingly soluble in water, allowing for gradual release of calcium and phosphorus in applications such as animal feed and fertilizer, ensuring their availability for absorption and utilization.

3. pH buffering: Calcium Hydrogenphosphate Dihydrate can act as a buffering agent, helping to stabilize the pH in certain applications, such as food and beverage formulations.

4. Excipient functionality: In the pharmaceutical industry, Calcium Hydrogenphosphate Dihydrate serves as an excipient, providing bulk, aiding in tablet formation, and contributing to the overall physical properties of solid dosage forms.

5. Regulatory compliance: Calcium Hydrogenphosphate Dihydrate complies with relevant regulations and standards for its specific applications, ensuring its safety and suitability for use in food, pharmaceutical, and animal feed industries.

Chemical Properties	white crystalline solid
Chemical Properties	Dibasic calcium phosphate dihydrate is a white, odorless, tasteless powder or crystalline solid. It occurs as monoclinic crystals.
Uses	pharmaceutic aid (tablet base).

Dibasic calcium phosphate dihydrate is widely used in tablet formulations both as an excipient and as a source of calcium and phosphorus in nutritional supplements. It is one of the more widely used materials, particularly in the nutritional/health food sectors. It is also used in pharmaceutical products because of its compaction properties, and the good flow properties of the coarsegrade material. The predominant deformation mechanism of dibasic calcium phosphate coarse-grade is brittle fracture and this reduces the strain-rate sensitivity of the material, thus allowing easier transition from the laboratory to production scale. However, dibasic calcium phosphate dihydrate is abrasive and a lubricant is required for tableting, for example about 1% w/w of magnesium stearate or about 1% w/w of sodium stearyl fumarate is commonly used.
Two main particle-size grades of dibasic calcium phosphate dihydrate are used in the pharmaceutical industry. The milled material is typically used in wet-granulated, roller-compacted or slugged formulations. The ‘unmilled’ or coarse-grade material is typically used in direct-compression formulations.
Dibasic calcium phosphate dihydrate is nonhygroscopic and stable at room temperature. However, under certain conditions of temperature and humidity, it can lose water of crystallization below 1008℃. This has implications for certain types of packaging and aqueous film coating since the loss of water of crystallization appears to be initiated by high humidity and by implication high moisture vapor concentrations in the vicinity of the dibasic calcium phosphate dihydrate particles.
Dibasic calcium phosphate dihydrate is also used in toothpaste and dentifrice formulations for its abrasive properties.
