4-(3-Methoxy­phen­oxy)butyric acid

摘要

In the title compound, C11H14O4, an inter­mediate for the synthesis of a new kind of estrogen receptor modulator, all non-H atoms lie on a common plane (r.m.s. deviation = 0.0472 Å). All C—C bonds in the side chain are in a trans conformation, and the hydroxyl group is also trans to the methyl­ene chain. In the crystal structure, mol­ecules form centrosymmetric dimers showing a head-to-head arrangement which is stabilized by O—H⋯O hydrogen bonds. A weak C—H⋯O contact is also present.
