2-Hy­droxy-N,N,N-trimethyl-3-tetra­decyl­oxypropan-1-aminium bromide

In the crystal structure of the title compound, C₂₀H₄₄NO₂⁺·Br⁻, the cation and anion are connected via an O—H...Br hydrogen bond, forming an ionic pair. The cation is disordered over two conformations related by a mirror plane, and the anion is situated on a mirror plane so that the asymmetric unit contains half of the ionic pair. The long alkyl chain in the cation adopts an all-trans conformation. The crystal packing exhibits weak inter­molecular C—H...O inter­actions.
