title: Allyl 4-hydroxy-phenyl carbonate.
abstract: The title mol-ecule, C(10)H(10)O(4), is a functionalized carbonate used in the synthetic route to organic glasses. The central CH fragment of the allyl group is disordered over two positions, with occupancies in a 0.758 (10):0.242 (10)ratio. This disorder reflects the torsional flexibility of the oxygen-allyl group, although both disordered parts present the expected anti-clinal conformation, with O-CH(2)-CH=CH(2) torsion angles of -111 (2) and 119.1 (4)°. The crystal structure is based on chains parallel to [010], formed by O⋯H-O hydrogen bonds involving hydroxyl and carbonyl groups as donors and acceptors, respectively. The mol-ecular packing is further stabilized by two weak C-H⋯π contacts from the benzene ring of the asymmetric unit with two benzene rings of neighboring mol-ecules.
