Product name: 2,2,6,6-Tetramethyl-4-piperidone
CAS No.: 826-36-8
Molecular formula: C9H15NO
Applications:
Core Industrial Applications (full-chain upstream nucleus)
1. HALS core feedstock (~90% consumption)
Foundation intermediate for all hindered-amine light stabilizers; two key downstream branches:
1. Carbonyl hydrogenation → tetramethylpiperidinamine, synthesizing mainstream plastic/coating stabilizers 770, 944, 622, 292;
2. Direct alkylation and esterification for low-molecular-weight light stabilizer monomers; used in PP/PE film, ABS, polyurethane, outdoor coatings and rubber — UV aging suppression and anti-yellowing.
2. TEMPO oxidation catalyst precursor
Oxidation to tetramethylpiperidine N-oxyl radical (TEMPO) — selective oxidant for pharma, fragrance and fine chemicals; essential for alcohol and polysaccharide oxidation.
3. Pharmaceutical and agrochemical intermediates
1. Heterocyclic drug and anti-inflammatory API building blocks;
2. Agricultural polymer anti-photoaging additive intermediate.
4. Other fine chemicals
Nylon heat stabilizers, metal corrosion inhibitors, organic synthesis Schiff-base ligands.
