Malononitril bụ ihe siri ike na-enweghị ụcha (<25°C) nke nwere isi ihe na-esi na 220°C yana ebe ọkụ ọkụ nke 112°C. Nnukwu ike ndọda ya bụ D434.2:1.0488. Ọ na-agbaze na mmiri, na-agbaze na ihe mgbaze organic dị ka benzene na mmanya na-aba n'anya, na-adịghị edozi na mmiri oyi, carbon tetrachloride, petroleum ether na xylene. Malononitrile nwere abụọ cyano- na otu reactive methylene, na ike kemịkalụ ọrụ, ma carbon na nitrogen atọm nwere ike mepụta mgbakwunye mmeghachi omume; nwere ike polymerize. Ọ na-egbu egbu, na-akpata ọgba aghara neurocentric, na-emebi emebi na mgbawa.
Ngwa:
(1) Malononitrile bụ akụrụngwa maka nkwadebe nke 2-amino-4,6-dimethoxypyrimidine na 2-chloro-4,6-dimethoxypyrimidine, nke a pụrụ iji na-emepụta sulfonylurea herbicides dị ka bensulfuron na pyrimethamiphosulfuron, wdg. A na-ejikwa ya rụpụta herbicide diflubenzuron, nke a na-eji na-emepụta ọgwụ diuretic na nkà mmụta ọgwụ.
(2) Organic njikọ akụrụngwa. Na nkà mmụta ọgwụ, a na-eji ya maka njikọ nke vitamin B1, aminopterin, aminobenzyl pteridine na usoro ọgwụ ndị ọzọ dị mkpa. Ọ nwere ihe dị mkpa eji eme ihe na-esiji, pesticides na ngwa ndị ọzọ. Enwere ike iji ya dị ka ihe na-emepụta ọla edo.
