TEMPO CAS#2564-83-2

2,2,6,6-Tetramethylpiperidine is a product that is used for the most diverse purposes because of its strong basicity, for example, as a light stabilizer for polyolefins, as a cocatalyst in olefin polymerizations (Ziegler catalysts), as a building block for the synthesis of pharmaceuticals and crop protection products, as a cocatalyst in the synthesis of dichloroacetyl chloride. The 4-unsubstituted 2.2.6,6-tetramethylpiperidine is generally prepared from the corresponding 4-oxo compound. It is known that triacetonamine can be converted by hydrazine to the hydrazone, which is then cleaved in the presence of alkali into 2,26,6-tetramethylpiperidine and nitrogen.
