Pyridinium chlorochromate (PCC) is a red–orange salt with the formula C5H5NH[CrO3Cl]. It is a reagent in organic synthesis used primarily for the oxidation of alcohols to form carbonyls. A variety of related compounds are known with similar reactivity. Although no longer widely used PCC offered the advantage of the selective oxidation of alcohols to aldehydes whereas many other reagents were less selective. Disadvantages to using PCC are the tedious reaction workup and its toxicity.
