Molecular Structure: (CrO3) Chromic acid, polymer-supported; Chromic anhydride; Chromium trioxide; Chromiumoxide; Chromic acid; ...
Properties
Transport:UN 1463
Density:2.7g/cm3
Stability:Stable. Strong oxidizer. Reacts with most organic material in a violent and often explosive fashion. Moisture sensitive.
Solubility:Highly soluble
Appearance:dark red crystals or powder
Specification:Chromium trioxide (CAS NO.10043-01-3) is highly toxic, corrosive and carcinogenic. It is the main example of the environmental hazard known as "hexavalent chromium". The related chromium (III) derivatives are not particularly dangerous, thus reductants are used to destroy chromium(VI) samples. Chromium trioxide, being a powerful oxidizer, will ignite some organic materials (such as ethanol) on contact.
Packinggroup: II

Brown solid
Flake, ground powder form
Dark-red flakes or powder [Note: Often used in an aqueous solution (H2CrO4)].
Usage:Medication (vet).
