2,2,6,6-Tetramethylpiperidine（Cat No.:R015821）is a sterically hindered, non-nucleophilic secondary amine widely used in organic synthesis and polymer chemistry. Its piperidine ring is substituted with four methyl groups at positions 2 and 6, conferring exceptional steric bulk and thermal stability. This compound is a key precursor to hindered amine light stabilizers (HALS), which protect polymers from UV-induced degradation. It also serves as a base or ligand in various catalytic and synthetic applications, where its minimal nucleophilicity prevents unwanted side reactions, making it highly effective in selective transformations and radical chemistry.
