'''Cadalene''' or '''cadalin''' (4-isopropyl-1,6-dimethylnaphthalene) is a [polycyclic aromatic hydrocarbon](/source/polycyclic_aromatic_hydrocarbon) with a chemical formula C<sub>15</sub>H<sub>18</sub> and a [cadinane](/source/cadinane) skeleton. It is derived from generic [sesquiterpene](/source/sesquiterpene)s, and ubiquitous in [essential oil](/source/essential_oil)s of many [higher plant](/source/higher_plant)s.<ref>{{cite journal|doi=10.1590/S0103-50532003000300004|title=Aliphatic and aromatic hydrocarbons in tropical recent sediments of Campos dos Goytacazes, RJ, Brazil|year=2003|last1=Gomes|first1=Alexandre de O.|last2=Azevedo|first2=Débora de A.|journal=Journal of the Brazilian Chemical Society|volume=14|issue=3|pages=358 |doi-access=free}}</ref>

Cadalene, together with [retene](/source/retene), [simonellite](/source/simonellite) and [ip-iHMN](/source/ip-iHMN), is a [biomarker](/source/biomarker) of [higher plant](/source/higher_plant)s, which makes it useful for [paleobotanic](/source/paleobotanic) analysis of rock [sediment](/source/sediment)s.

The ratio of retene to cadalene in sediments can reveal the ratio of the genus ''[Pinaceae](/source/Pinaceae)'' in the biosphere.<ref>{{cite journal|journal=Geophysical Research Abstracts|volume=7|pages=10201|year=2005|title=Vascular plant biomarkers as ancient vegetation proxies and their stratigraphic use for tracing paleoclimatic changes during Jurassic in Western Europe|author1=Hautevelle, Y. |author2=Michels, R. |author3=Malartre, F. |author4=Trouiller, A. |url=http://www.cosis.net/abstracts/EGU05/10201/EGU05-J-10201.pdf|format=abstract page}}</ref>
