Sharaxaada Alaabta:
Malononitril waa mid adag oo aan midab lahayn (<25°C) oo leh barta karkarinta 220°C iyo barta ifaysa ee 112°C. Cuf-jiitaankeeda gaarka ah waa D434.2:1.0488. Waxay ku milmi kartaa biyaha, waxay ku milmi kartaa dareeraha organic sida benzene iyo alkohol, aan lagu milmin biyaha qabow, tetrachloride carbon, ether petroleum iyo xylene. Malononitrile waxay leedahay laba cyano- iyo hal methylene fal-celin leh, oo leh firfircooni kiimiko oo xoog leh, labadaba kaarboon iyo atamka nitrogen waxay fulin karaan falcelin dheeri ah; polymerize karaa. Waa sun, sababa xanuunada neurocentric, waa daxal iyo qarax.
Codsiga:
(1) Malononitrile waa alaabta ceeriin ee diyaarinta 2-amino-4,6-dimethoxypyrimidine iyo 2-chloro-4,6-dimethoxypyrimidine, kaas oo loo isticmaali karo in lagu soo saaro herbicides sulfonylurea sida bensulfuron iyo pyrimethamiphosulfuron, iwm. Waxa kale oo loo isticmaali karaa in lagu soo saaro herbicide diflubenzuron, kaas oo loo isticmaalo soo saarista dawooyinka diuretic ee daawada.
(2) Walxaha cayriin ee isku dhafan ee dabiiciga ah. Daawada, waxaa loo isticmaalaa isku-dhafka fitamiin B1, aminopterin, aminobenzyl pteridine iyo taxane kale oo muhiim ah. Waxay leedahay isticmaalka muhiimka ah ee dheeha, sunta cayayaanka iyo codsiyada kale. Waxa kale oo loo isticmaali karaa soosaar ahaan dahabka. Waxaa hadda loo isticmaalaa gudaha Shiinaha inta badan soosaarka aminopterin, bensulfuron, 1,4,5,8-naphthalenetetracarboxylic acid iyo alaabooyinka taxanaha pyrimidine.
(3) Loo isticmaalo dawooyinka, waa dhexdhexaad ka mid ah dawada aminopterin.
(4) Waxaa loo isticmaali karaa sida alaabta ceeriin ee isku-dhafka dabiiciga ah, dhexdhexaadiyeyaasha dawooyinka iyo dareerayaasha organic.
