Description

White to off-white solid; [Acros Organics MSDS]

Sources/Uses

Used as a chelating agent; [Merck Index] "An iron chelating agent with properties like EDETIC ACID. DTPA has also been used as a chelator for other metals, such as plutonium." [ChemIDplus] Used in cosmetic products, in industrial metal extraction, and therapeutically; [ExPub: TERIS]

Comments

The calcium salt causes fetal death and teratogenic effects in mice (thought to be associated with the chelation of essential divalent cations such as zinc); [REPROTOX] Causes convulsions and chronic pulmonary edema in intraperitoneal lethal-dose studies of rats (LD50 = 587 mg/kg); [RTECS] An eye irritant; [Acros Organics MSDS] See "Edetic acid."
