The Cornforth reagent (pyridinium dichromate; PDC), is the complex of chromium(VI) oxide with aqueous pyridine, with the chemical formula (C5H5NH)2Cr2O7. Like pyridinium chlorochromate (PCC), it is used as an oxidising agent to convert alcohols to aldehydes and ketones. Compared with PCC, PDC presents the advantage of being less acidic.
