white to off-white crystalline powder

??

2,5-Dithiobiurea is used in radiopharmaceutical imaging, inhibiting enzyme function, kidney function study and to treat toxic metal poisoning. It is also used in co-crystals development and in the field of nonlinear optics to generate new coherent wavelengths

?? ??

Brown powder.

??? ?? ??

Insoluble in water.

?? ???

Hydrazodicarbothioamide is related to dithiocarbamates. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides.

????

The flash point of Hydrazodicarbothioamide has not been determined, but Hydrazodicarbothioamide is probably combustible.
