The smell and pungent taste, can dissolve in water, alcohol, ether and benzene. When the carbon atom of the ring is replaced, the boiling point and the melting point increase; when the nitrogen atom is replaced, the boiling point and the melting point of the compound is reduced. Chloride, bromide, iodide, alkylation and acylation reactions occur easily. The molecular formula is C3H4N2, which is toxic to the ingestion of the eye, and has a stimulating effect on the eyes, skin and respiratory tract.
