Indanes are compounds containing an indane moiety, which consists of a cyclopentane fused to a benzene ring. Pallidol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Pallidol can be found in grape wine, which makes pallidol a potential biomarker for the consumption of this food product. Pallidol is a resveratrol dimer. It can be found in red wine, in Cissus pallida or in Parthenocissus laetevirens .
