'''Cadalene''' or '''cadalin''' (4-isopropyl-1,6-dimethylnaphthalene) is a polycyclic aromatic hydrocarbon with a chemical formula C<sub>15</sub>H<sub>18</sub> and a cadinane skeleton. It is derived from generic sesquiterpenes, and ubiquitous in essential oils of many higher plants.<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, simonellite and ip-iHMN, is a biomarker of higher plants, which makes it useful for paleobotanic analysis of rock sediments.
The ratio of retene to cadalene in sediments can reveal the ratio of the genus ''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>
