Full Description

Dicalcium phosphate (CAS 7757-93-9) is calcium hydrogen orthophosphate (CaHPO4). It is used as a mineral supplement and source of calcium and phosphorus in animal feed, as a leavening agent and food additive, as a mild abrasive and mineral source in dental products, and as a tableting aid and excipient.

Frequently Asked Questions

What does dicalcium phosphate do?

Dicalcium phosphate (CAS 7757-93-9, CaHPO4) is calcium hydrogen orthophosphate. It supplies calcium and phosphorus as a mineral supplement in animal feed, acts as a leavening agent and dough conditioner in food, serves as a tableting aid and bulking excipient, and provides a mild abrasive/mineral source in dentifrices.

What is the difference between calcium phosphate and dicalcium phosphate?

"Calcium phosphate" is a general term covering several calcium-phosphorus salts (mono-, di-, and tricalcium phosphate). Dicalcium phosphate specifically is calcium hydrogen orthophosphate, CaHPO4, with one acidic hydrogen and a 1:1 calcium-to-phosphate ratio.

What is the difference between dicalcium phosphate dihydrate and anhydrous?

Both are CaHPO4 (CAS 7757-93-9), but the dihydrate carries two waters of crystallization and the anhydrous form does not. The forms differ in flow, density, and stability, which matters for tableting and feed applications; state the form required when ordering.

What is the CAS number and HS code for dicalcium phosphate?

It is CAS 7757-93-9, formula CaHO4P (CaHPO4), in the acids and salts family. HS code 2835.25 (calcium hydrogenorthophosphate, "dicalcium phosphate"). Specify feed, food, or pharmaceutical grade on the order.

What is the cost of bulk dicalcium phosphate?

Bulk pricing depends on grade, hydrate form, packaging, volume, and destination. Request a quote with your tonnage, grade, and ship-to location; a CoA and SDS accompany each shipment.
