Calcium phosphate tribasic CAS#12167-74-7

The PhEur 6.4 states that tribasic calcium phosphate consists of a mixture of calcium phosphates. It contains not less than 35.0% and not more than the equivalent of 40.0% of calcium. The USP32– NF27 specifies that tribasic calcium phosphate consists of variable mixtures of calcium phosphates having the approximate composition 10CaO·3P2O5·H2O. This corresponds to a molecular formula of Ca5(OH)(PO4)3 or Ca10(OH)2(PO4)6.
Tribasic calcium phosphate is a white, odorless and tasteless powder. col hexagonal crystal(s) [CRC10]

Product Application of Calcium phosphate tribasic CAS#12167-74-7

Calcium phosphate tribasic is the mineral component of bones and teeth; it has been used therapeutically as a prosthetic aid and in the prevention and treatment of osteoporosis. Employed in tissue replacement for repairing bony defects and acts as drug carrier for drug delivery to the bone. Hydroxyapatite nanopowders, incorporated in biodegradable polymer composites or deposited on biocompatible substrates, have been shown to promote adhesions and proliferation of bone-forming (osteoblast) cells. It is also the starting material for the production of phosphoric acid and fertilizers.
