Pyridine is weakly basic and is miscible with water. It is extremely flammable and when inhaled or ingested it becomes toxic. If exposed to pyridine, we may feel nausea, asthmatic breathing, vomiting, headache, laryngitis, and coughing. It is widely used in the precursor to agrochemicals and pharmaceuticals. Also, it is used as an essential reagent and organic solvent.
