  • Title: The concomitant crystallization of two polymorphs of 1-deoxy-alpha-D-tagatose.
    Author: Jones NA, Jenkinson SF, Soengas R, Izumori K, Fleet GW, Watkin DJ.
    Journal: Acta Crystallogr C; 2007 Jan; 63(Pt 1):o7-10. PubMed ID: 17206062.
    Abstract:
    The crystalline form of 1-deoxy-D-tagatose, C6H12O5, is shown to be 1-deoxy-alpha-D-tagatopyranose; the absolute configuration is determined by use of D-lyxono-1,4-lactone as the starting material. The title compound crystallized as concomitant polymorphs from a mixture of ethyl actate and methanol. Although the melting points of the materials differ by 7 K, the molecular conformations are almost identical and, in both polymorphs, each molecule is subject to four O-H...O hydrogen bonds.
