Pyridinium chlorochromate (PCC) is a yellow-orange salt with the formula [C₅H₅NH]⁺[CrO₃Cl]⁻. It is a reagent in organic synthesis used primarily for oxidation of alcohols to form carbonyls. A variety of related compounds are known with similar reactivity. PCC offers the advantage of the selective oxidation of alcohols to aldehydes or ketones, whereas many other reagents are less selective.
