Chemical Properties

WHITE TO OFF-WHITE FLAKES

Safety Profile

Poison by intraperitoneal route. When heated to decomposition it emits very toxic fumes of Clí and NOx.

Purification Methods

Purify it by recrystallisation from EtOH or aqueous EtOH. It sublimes at 150o/3mm. [den Hertog et al. Recl Trav Chim Pays-Bas 69 673 1950, Schikh et al. Chem Ber 69 2604 1936, Beilstein 20 I 81, 20 III/IV 2503, 20/5 V 422.]
