2-(4-Hy-droxy-phen-yl)-3-(trimethyl-sil-yl)propanaminium chloride.

In the title crystal structure, C12H22NOSi+·Cl−, anions and cations are linked via O—H⋯Cl, N—H⋯Cl and N—H⋯O hydrogen bonds to form a two-dimensional network parallel to (101). Within the hydrogen-bonded network, R42(22) ring motifs are stacked along [010].
