Chemical structure

Properties

Bright yellow needles, plates, flakes. Faint chlorine odor, burning taste. Dec explosively at ≈155°. Decompn is accelerated by contact with metals. Very slightly sol in water; sparingly sol in alcohol; slightly sol in glycerol, glyceryl triacetate (1:100), vegetable oils, ether, chloroform. Practically insol in carbon tetrachloride and liquid petrolatum. Oil solns are generally made by diluting a triacetin (glyceryl triacetate) soln of chloroazodin with oil. Solns of chloroazodin in glycerol and in alcohol dec rapidly on warming; all solns dec on exposure to light.
