Chromium trioxide or Chromic acid (anhydrous) is the inorganic compound with the formula CrO3. It is available in flakes or in aqueous solution.
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.

Millions of kilograms are produced annually, mainly for electroplating. Chromium trioxide is a powerful oxidiser and a carcinogen. Chromium trioxide is a chromium oxide composed of a single chromium bound (oxidation state +6) to three oxygens; the acidic anhydride of chromic acid. ChEBI Chromium trioxide, anhydrous appears as a dark purplish red solid.
Articles of chromium trioxide are included as well.

Chromium trioxide is also considered highly toxic for aquatic and marine environments. Given such toxicity concerns, the use of chromium trioxide for industrial purposes is subject to various regulations, such as the EU Directive 2004/37. Chromium trioxide is also know by trade names, such as chromic anhydride and Chromium VI Oxide.

This chromium trioxide/acetone/sulfuric acid reagent is often referred to as the Jones reagent, and oxidation of alcohols with this reagent is called Jones oxidation. 48 Jones oxidation is especially useful for molecules that contain alkenyl or alkynyl groups. 49 Oxidation of alcohols is usually faster in acetone than in acetic acid, and using a large excess of acetone protects the ketone Authorization of chromium trioxide – Requirements to be fulfilled by the downstream user. Since the EU has approved the authorization of the CTAC submission on 18 December 2020 which covers the gravure printers and cylinder makers as downstream users, the individual downstream user must comply with additional authorization conditions to further use chromium trioxide.
