Leukotriene B4, 5S,12R-dihydroxy-6,8,10,14(Z,E,E,Z)-eicosatetraenoic acid, is a twenty carbon tetra-unsaturated fatty acid. No crystal forms of leukotriene B4 (LTB4) are known in the art. The present inventors have discovered a crystal form of LTB4 and the present invention therefore relates to crystal forms of LTB4 in general, and the novel crystal form A of LTB4 in particular.
