Calcium phosphate, dibasic

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 581323

CAS#: 7757-93-9

Description: Dicalcium phosphate is the calcium phosphate with the formula CaHPO4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO42– anion involves the removal of two protons from phosphoric acid, H3PO4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate. Dicalcium phosphate is used as a food additive, it is found in some toothpastes as a polishing agent and is a biomaterial.[
