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.[1]
