Abstract: In the title compound, C11H10O3, there is an intramolecular O-HO hydrogen bond generating an S(6) ring motif. The O atom of the hydroxy group deviates by 0.0200 (1) Å from the benzene ring to which it is attached. The propyne group is almost linear, the C-CC 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, molecules are linked via C-HO hydrogen bonds, forming infinite C(11) chains running parallel to . These chains are linked by a pair of C-HO hydrogen bonds, enclosing R22(8) inversion dimers, forming a corrugated two-dimensional network lying parallel to (103).
