Also known as pyrophosphates, pyrophosphate, diphosphates

In chemistry, pyrophosphates are phosphorus oxyanions that contain two phosphorus atoms in a linkage. A number of pyrophosphate salts exist, such as disodium pyrophosphate () and tetrasodium pyrophosphate (), among others. Often pyrophosphates are called diphosphates. The parent pyrophosphates are derived from partial or complete neutralization of pyrophosphoric acid. The pyrophosphate bond is also sometimes referred to as a phosphoanhydride bond, a naming convention which emphasizes the loss of water that occurs when two phosphates form a new bond, and which mirrors the nomenclature for anhyd

Si definisce comunemente pirofosfato l'anione, il sale e l'estere dell'acido pirofosforico. Originariamente preparati riscaldando i fosfati (da cui il prefisso greco pyro-, fuoco), i pirofosfati sono buoni agenti complessanti per gli ioni metallici (come il calcio e molti metalli di transizione) e sono ampiamente utilizzati nell'industria chimica.
