Protocatechual alcohol ( 3,4-dihydroxybenzyl alcohol ) is structurally derived from both benzyl alcohol and catechol .
It can be prepared from protocatechualdehyde in methanolic solution by reduction with hydrogen / Raney nickel at room temperature and normal pressure. It occurs naturally as a component of olive oil and in some living things.
