چکیده
In the title compound, C11H10O3, there is an intra-molecular O-H⋯O hydrogen bond generating an S(6) ring motif. The O atom of the hy-droxy group deviates by 0.0200 (1) Å from the benzene ring to which it is attached. The propyne group is almost linear, the C-C C angle being 177.83 (15)°, and is almost coplanar with the benzene ring; the C-C-O-C torsion angle being only -1.1 (2)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming infinite C(11) chains running parallel to [103]. These chains are linked by a pair of C-H⋯O hydrogen bonds, enclosing R 2 (2)(8) inversion dimers, forming a corrugated two-dimensional network lying parallel to (103).
