APPLICATIONS
2-Piperidone, a keto-hydropyridine, is the 6-membered lactam structure compound (delta-valerolactam).  Lactam structure compounds including delta-valerolactam are good organic solvents soluble in water. Cyclic amides and analogues including N-alkyl lactams are biologically active nucleuses in pharmacologicals and flavorings. Lactams are widely used in artificial fibre industry. They are polymerizable and used as nylon precursors. They have excellent applications as solvents and as intermediates for organic synthesis. They are used in the aqueous carrier medium and amide penetrants in inks and water soluble paints. 4-Piperidone, a cyclic amide with ketone at para position, and its N-alkyl substituted derivatives are used in:
  • Alkene formation at the position of former carbonyl group. Alkene bonds are abundant in natural compounds
  • Sulfur compound removals
  • UV stabilizer products
  • Multicyclic hetero compounds and fused ring system compounds
  • Pharmaceutical synthesis including narcotic analgesics and digestive system drugs

    • 2,2,6,6-Tetramethylpiperidinone, cyclic amide containing ketone at 4 position and polymethyl branches, is an intermediate for UV-stabilizers and other organic chemicals
