About this item

IUPAC name	oxo(oxochromiooxy)chromium
canonical smiles	O=[Cr]O[Cr]=O
inchi	InChI=1S/2Cr.3O
inchi key	QDOXWKRWXJOMAK-UHFFFAOYSA-N
molecular formula	Cr2O3
synonyms	Chromium(III) oxide 1308-38-9 Chromia Dichromium trioxide Chromium sesquioxide
Compound Description	Dichromium trioxide is a chromium oxide. Chromium oxide is an oxide of chromium that occurs in nature as the rare mineral eskolaite. It is commonly used as pigment, under the name viridian, in paints, inks, and glasses. Chromium is a chemical element which has the symbol Cr and atomic number 24. It is found naturally occuring in rocks, animals, plants, and soil, and is usually mined as chromite ore. Chromium is most toxic in its +6 oxidation state ) due to its greater ability to enter cells and higher redox potential. Trivalent chromium ) however, is biologically necessary for sugar and lipid metabolism in humans.
