In chimica organica gli atomi che formalmente sostituiscono il carbonio nelle molecole etero-aromatiche sono, solitamente, ossigeno, azoto e zolfo. Nella piridina la coppia di non legame dell'azoto fa intuire che il momento dipolare sia orientato dall'azoto verso il carbonio 3. Questo fa intuire che il vettore che rappresenta il momento dipolare sia diretto verso l'eteroatomo stesso. I composti flavonoidi devono il loro nome al catione flavilio o 2-fenil-benzopirillio, se considerato come derivato fenilico del benzopirillio. Quando le antocianidine sono glicosilate, cosa che spesso accade all'altezza del carbonio 3, prendono il nome di antocianine.
