Cupric Pyrophosphate is an inorganic salt formed by the reaction of copper(II) ions with pyrophosphate anions. It exists in several hydration states, most commonly as the trihydrate (Cu₂P₂O₇·3H₂O) or tetrahydrate (Cu₂P₂O₇·4H₂O), and is commercially available as a fine, free-flowing powder with high chemical purity (typically ≥98%).
Sodium pyrophosphate decahydrate (CAS 13472-36-1), also known as tetrasodium pyrophosphate decahydrate (TSPP decahydrate), is an inorganic compound with the chemical formula Na₄P₂O₇·10H₂O. It belongs to the pyrophosphate family and exists as a white, crystalline powder or colorless crystals that are freely soluble in water, forming an alkaline solution.
