'''Piridina''' [[konposatu aromatiko]] heteroziklikoa (C<sub>5</sub>H<sub>5</sub>N). [[Harrikatz]]aren alkaternan aurkitu zuen Anderson-ek 1846an. [[Likido]] kolorgea, sukoia eta oso usain txarrekoa da (arrain ustelaren usaina du). Egituraz, [[bentzeno]]aren antza du; bien arteko alde bakarra da bentzenoaren CH talde baten ordez [[nitrogeno]] atomo bat izatea. Uretan eta disolbatzaile organikoetan ongi urtzen da. [[Harrikatz|Ikatzaren]] alkaternaren destilazioz, edo azetaldehidoaren eta amoniakoaren sintesiaren bidez lortzen da. Oso gai toxikoa da. [[Bitamina]]k eta [[droga]]k sintetizatzeko, [[disolbatzaile]] gisa, ehungintzan tindaketan laguntzeko eta abarretarako erabiltzen da.
