27-Norcholestane, is a
chemical compound with the formula C
26H
46, that is a steroid derivative. 27-Norcholestane is used as a
biomarker to constrain the source age of sediments and petroleum through the ratio between
24-norcholestane and 27-norcholestane (norcholestane ratio, NCR), especially when used with other age diagnostic biomarkers, like
oleanane.
