Anwendungen

Extensively finds applications as a base, a nucleophile and a solvent. Used for the production of dipiperidinyl dithiuram tetrasulfide, which is used as a rubber vulcanization accelerator. It is commonly used in solid phase peptide synthesis (F-MOC Chemistry) and in chemical degradation reactions (sequencing of DNA). Used in making rubber, curing epoxy resins and in fine chemicals, and pharmaceuticals.

Bemerkungen

The piperidine skeleton is present in several naturally occuring alkaloids, such as piperine, solenopsin, coniine, etc., and in a wide variety of pharmaceuticals, such as SSRI (Selective Serotonin Reuptake Inhibitors), Vasodilators, SERM (Selective Estrogen Receptor Modulators), Neuroleptics (Antipsychotics), Analeptics/Nootropics (Stimulants), etc. Piperidine is a strong organic base and reacts violently with oxidizers.
