PCC

Pyridinium Chlorochromate, a chemical compound used in the oxidation of 1'st and 2's degree alcohols to ketones and aldehydes. In the absence of H2O, the aldehjyde does not form the hydrate and the oxidation reaction stops at the aldehyde.

CH3-CH2-CH2-CH2-OH + PCC ---> CH3-CH2-CH2-COOH + Cr3^+
