What is Anhydrous Dicalcium Phosphate CAS 7757-93-9?

Anhydrous Dicalcium Phosphate CAS 7757-93-9 is calcium hydrogen phosphate with the formula CaHPO4. It is supplied as a white powder or granule and used as a concentrated calcium and phosphorus source in animal feed, plus as a food-grade mineral additive.

How is the anhydrous form different from dicalcium phosphate dihydrate?

The anhydrous form is CaHPO4 without crystal water, while the dihydrate is CaHPO4.2H2O. Removing the water increases nutrient density, so the anhydrous feed grade can supply more phosphorus per kilogram than the hydrated grade.

What phosphorus and calcium levels does this feed-grade product provide?

The listing specifies phosphorus of at least about 19.7-20.0% and calcium of at least 30.0%. This higher phosphorus density helps reduce the amount of product needed in a feed formulation compared with a hydrated dicalcium phosphate.

What are the main animal-feed benefits?

It supports bone and tooth development in growing livestock and poultry, helps prevent rickets and osteomalacia, and improves eggshell hardness in laying hens. It is chemically neutral enough to be blended with vitamins and many other feed ingredients.

Is Anhydrous Dicalcium Phosphate also used in food products?

Yes. Food-grade calcium hydrogen phosphate can be used as a calcium supplement, dough conditioner, leavening aid or mineral fortifier. It is also used in toothpaste as a mild polishing and abrasive agent.

Why is low fluorine content important?

Excess fluorine can be harmful in long-term animal diets. The low-fluorine specification of no more than 0.18% helps keep feed formulations within acceptable fluoride limits for livestock and poultry.

What are the solubility, pH and handling characteristics?

Anhydrous dicalcium phosphate is practically insoluble in water but dissolves in dilute mineral acids. The feed-grade material in this listing has a pH of about 3.5-5.5 under the stated test conditions, so keep it dry in closed packaging and confirm the grade is suitable for the intended feed or food formulation.

Product Description

Anhydrous Dicalcium Phosphate, CAS 7757-93-9, also known as calcium hydrogen phosphate, is the anhydrous salt CaHPO₄; the EC/EINECS number is 231-826-1.

Synonyms: calcium hydrogen phosphate; dibasic calcium phosphate; calcium monohydrogen phosphate; calcium phosphate dibasic.

CAS: 7757-93-9.

Molecular formula: CaHPO₄.

Molecular weight: 136.06 g/mol.

EC number: 231-826-1.

It is a white powder or granule with concentrated calcium and phosphorus content.

Feed grade typically provides at least about 19.7–20.0% phosphorus and at least 30.0% calcium.

The anhydrous form supplies more phosphorus per kilogram than the hydrated dihydrate form.

It supports bone and tooth development in growing livestock and poultry and improves eggshell hardness.

It is used in aquaculture to provide essential phosphorus and reduce unabsorbed-phosphorus water pollution.

It is used as a base ingredient in salt licks and mineral blocks for cattle and sheep.

Food grade is used as a calcium supplement, dough conditioner, leavening aid and mineral fortifier.

Confirm phosphorus, calcium, fluorine, arsenic, lead, cadmium, moisture, pH and particle size.

Store in tightly sealed bags in a cool, dry, ventilated warehouse, away from rain and moisture.

Keep bags sealed when not in use to maintain the anhydrous state and store away from toxic or hazardous materials.

Confirm packaging with the requested quantity and destination requirements.
