1,1'-(Piperazine-1,4-di-yl)dipropan-2-ol.

The asymmetric unit of the crystal contains one-fourth of the title compound, C(10)H(22)N(2)O(2), with the centre of the piperazine ring located at a site of 2/m symmetry. The piperazine ring adopts a chair conformation. The methine and methylene C atoms of the 2-hydroxypropyl groups show symmetry-imposed disorder over two equally occupied and mutually exclusive sets of positions. Only intra-molecular O-H⋯N contacts are observed.
