Potassium permanganate is a nephrotoxin and hepatotoxin, as well as a corrosive agent in the gastrointestinal tract. On the other hand, the reaction is an Oxidation-reduction reaction. Physical properties: KMnO 4 is found as a bright purple colored crystalline solid. As in acid-base titrations, the endpoint of a redox titration is often detected using an indicator. On the other hand, in 1979, Corey and Schmidt reported [11] that reaction of saturated primary alcohols with PDC, using dimethylformamide (Me2NCHO, DMF) as solvent, results in oxidation to carboxylic acids rather than aldehydes. The aldehyde can then be subjected to the conditions of the Pinnick oxidation using sodium chlorite.
