Uses

CAS 6091-44-7, known as Piperidine Hydrochloride, is primarily used as a crucial intermediate in synthesizing various pharmaceuticals (like anti-Parkinson’s drugs), a reagent in complex organic chemistry (Mannich reactions, asymmetric hydrogenation), and in advanced materials like perovskite solar cells, serving as a building block for new drugs and chemical compounds in research and industry.

Pharmaceutical Industry

  • API Synthesis: Intermediate for drugs such as Biperiden (anti-Parkinson’s), Clocapramine (antidepressant), and Tolperisone (muscle relaxant).
  • Drug Development: Used to create peripheral serotonin 5-HT3 receptor ligands and other pharmacologically active molecules.

Chemical Synthesis & Research

  • Reagent: Used in important reactions like Mannich reactions, asymmetric hydrogenation, and chemoselective reductive amination.
  • Building Block: For creating quinoline selenium compounds and phthalazinone derivatives with potential therapeutic uses.
  • Analytical Standard: High-purity material used for method validation and quality control in labs.

Materials Science

  • Perovskite Devices: Acts as a precursor in the preparation of advanced perovskite solar cells and other related devices.

Other Uses & Properties

  • Solvent/Catalyst: Piperidine (the free base) has broader uses as a solvent and curing agent, with the hydrochloride salt serving related synthetic roles.
  • Neuroprotective/Immunomodulatory: Research indicates it can block dopamine receptors and potentially offer neuroprotection and immune effects.

 Applications

  • Intermediate for APIs:Key building block for Active Pharmaceutical Ingredients (APIs).
  • Anti-Parkinsonian Agents:Used to make Biperiden.
  • Antidepressants:Involved in synthesizing Clocapramine hydrochloride.
  • Muscle Relaxants:A precursor for Tolperisone.
  • Neuroprotection:Shows potential in developing treatments for Parkinson’s disease and other neurological conditions, as it can block dopamine receptors and has immunomodulatory properties.

 

Chemical & Research Applications

  • Organic Synthesis:Acts as a reactant or catalyst in various reactions, including Mannich reactions, asymmetric hydrogenation, and reductive amination.
  • Ligand Synthesis:Used to create peripheral serotonin 5-HT3 receptor ligands.
  • Phosphodiesterase Inhibitors:A reactant in synthesizing phthalazinone derivatives with potential as PDE4 inhibitors.
  • Materials Science:A precursor for perovskite-based devices, especially in solar cell research.

Other Uses (Related to Piperidine)

  • While the salt form (hydrochloride) is key, its parent compound, piperidine, is used as a solvent, rubber curing agent, and food additive, though safety precautions are vital
