Descrição geral

Pyridine is a heterocyclic compound and a toxic chemical, which is widely used as a solvent and intermediate in the production of dyes, rubber products, paints, textile water repellents, agricultural chemicals, chemical laboratories, manufacturing of piperidine, etc. It plays an important role in the sensory properties of cigarette smoke and exists as a volatile component in certain food products.

Aplicação

Pyridine may be used as an analytical reference standard for the quantification of the analyte in cigarette smoke using reversed-phase liquid chromatography/electrospray ionization tandem mass spectrometry (RP-HPLC–ESI-MS/MS).

Allosteric modulators of the metabotropic glutamate receptor subtype 5 (mGlu5) have exciting potential as therapeutic agents for multiple brain disorders. Translational studies with mGlu5 modulators have relied on mGlu5 allosteric site positron emission tomography (PET) radioligands to assess receptor occupancy
