Properties: Orange-red, monoclinic needles from benzene, mp 178°. Additional purification by sublimation in high vacuum, (bath temp 100°), mp 180°. bp760 ~185°. Further heating results in deflagration and explosion. Practically insol in cold water, hydrolyzed by boiling water. Slightly sol in benzene, abs ethanol, carbon disulfide. Handle with caution: May dec explosively on striking or at temps much above 100°.

Melting point: mp 178°; mp 180°

Boiling point: bp760 ~185°
