Calcium phosphate dibasic CAS#7757-93-9
Stability: Dibasic calcium phosphate remains stable when exposed to air and has a long shelf life.
Low Solubility: It is nearly insoluble in water, making it ideal for use in products that require minimal reactivity with water.
Acid Dissolution: Easily dissolves in diluted hydrochloric and nitric acids, offering versatility in various industrial applications.
Neutral pH: The compound maintains a neutral pH (7), making it suitable for formulations requiring balanced acidity.
Dibasic Calcium Phosphate exists in either an anhydrous form or as a dihydrate. It appears as a white, odorless, and tasteless powder that remains stable when exposed to air. While nearly insoluble in water, it dissolves easily in diluted hydrochloric and nitric acids. However, it does not dissolve in alcohol.
