4,6-Di-tert-butyl-2,3-di­hydroxy­benzalde­hyde

The title compound, C₁₅H₂₂O₃, crystallizes with two independent mol­ecules in the asymmetric unit. In each mol­ecule, one hy­droxy group (at position 2) is involved in an intra­molecular O—H...O hydrogen bond, and another one (at position 3) exhibits bifurcated hydrogen-bonding being involved in intra- and inter­molecular O—H...O inter­actions. In the crystal, O—H...O hydrogen bonds link alternating independent mol­ecules into chains running along [010].
