Ca5PO43I

Ca5(PO4)3I, also known as calcium phosphate iodide, is a chemical compound composed of calcium, phosphorus, oxygen, and iodine. It belongs to the family of calcium phosphates, which are salts of calcium and phosphoric acid. The compound has the chemical formula Ca5(PO4)3I, indicating that it contains five calcium ions, three phosphate ions, and one iodide ion.

Calcium phosphate iodide is typically prepared through the reaction of calcium hydroxide with phosphoric acid and iodine. The resulting compound is usually a white or off-white powder. It is soluble in water and can form various hydrates depending on the conditions of preparation and storage.

The primary use of calcium phosphate iodide is in the field of medicine, particularly in the treatment of hyperphosphatemia, a condition characterized by elevated levels of phosphate in the blood. It is used as a phosphate binder, helping to reduce the absorption of phosphate from the gastrointestinal tract and thereby lowering blood phosphate levels. This can be beneficial in conditions such as chronic kidney disease, where phosphate levels need to be controlled to prevent complications.

In addition to its medical applications, calcium phosphate iodide can also be used in the synthesis of other chemical compounds and as a component in various industrial processes. Its unique chemical properties make it a valuable substance in both medical and industrial contexts.
