Description

Purple or red-violet solid; [Hawley] Insoluble in water; [MSDSonline]

Sources/Uses

"Reduction of detonation of nitromethane"; [Hawley]

Comments

"The trivalent form of Cr is 500-1000 times less toxic than the hexavalent form. Organic Cr-containing complexes of toxicological importance have not been reported." [Nordberg, p. 718] CrIII compounds do not cause chrome ulcerations but may cause allergic dermatitis in workers with prior sensitization to CrVI compounds. [ILO Encyclo] CrIII is an essential trace mineral in the human diet. [ATSDR Case Studies] "Stable under recommended storage conditions." May be harmful after ingestion, inhalation, or skin contact; May damage eyes; [MSDSonline] See "Chromium."
