- 1,4-Naphthoquinone, of which the Vitamin K group compounds are derivatives
- 2,6-Naphthoquinone (amphi-naphthoquinone)
Naphthoquinones are also a class of natural phenolic compounds formed on a C6-C4 skeleton.
- 2-Methoxy-1,4-naphthoquinone, a compound found in Impatiens species
- Nigrosporin B
Uses as chemical precursors
Naphthoquinone can be used for the full synthesis of opiates (Gates synthesis), but it is a tedious and uneconomical process. Therefore, most of the opiate-type analgesics in use today are either directly extracted from Papaver somniferum or synthesized from the natural opiates, mainly from thebaine.
Diazonaphthoquinone is a diazo derivative of naphthoquinone.
