Malononitrile, yomwe imadziwikanso kuti dicyanomethane, cyanoacetonitrile, Malononitrile, ndi yolimba yopanda mtundu (<25°C) ndi kuwira kwa 220°C ndi kung'anima kwa 112°C. Mphamvu yokoka yake yeniyeni ndi D434.2:1.0488. Ndi sungunuka m'madzi, sungunuka mu zosungunulira organic monga benzene ndi mowa, insoluble m'madzi ozizira, carbon tetrachloride Chemicalbook, petroleum ether ndi xylene. Malononitrile ali awiri cyano- ndi imodzi zotakasika methylene, ndi amphamvu mankhwala ntchito, onse mpweya ndi asafe maatomu angathe kuchita kuonjezera zochita; akhoza polymerize. Ndi poizoni, zimayambitsa matenda a neurocentric, ndizowononga komanso zimaphulika. LD5012.9mg/kg mu makoswe ndi jekeseni wa intraperitoneal.
Ntchito:
(1) Malononitrile ndi zopangira zopangira 2-amino-4,6-dimethoxypyrimidine ndi 2-chloro-4,6-dimethoxypyrimidine, zomwe zingagwiritsidwe ntchito popanga mankhwala a herbicides a sulfonylurea monga bensulfuron ndi pyrimethamiphosulfuron, ndi zina zotero. amagwiritsidwanso ntchito popanga herbicide diflubenzuron, yomwe imagwiritsidwa ntchito popanga mankhwala okodzetsa muzamankhwala.
(2) Organic kaphatikizidwe zipangizo. Mu mankhwala, izo ntchito synthesis vitamini B1, aminopterin, aminobenzyl chemicalbook pteridine ndi mndandanda wa mankhwala ena ofunika. Imagwiritsidwa ntchito kwambiri mu utoto, mankhwala ophera tizilombo ndi ntchito zina. Itha kugwiritsidwanso ntchito ngati chochotsera golide. Tsopano ntchito ku China makamaka kupanga aminopterin, bensulfuron, 1,4,5,8-naphthalenetetracarboxylic asidi ndi pyrimidine mndandanda mankhwala.
(3) Yogwiritsidwa ntchito mu mankhwala, ndi yapakatikati mwa mankhwala aminopterin.
(4) Itha kugwiritsidwa ntchito ngati zida zopangira organic synthesis, intermediates mankhwala ndi zosungunulira organic.
