    Malononitril jẹ alagbara ti ko ni awọ (<25°C) pẹlu aaye gbigbọn ti 220°C ati aaye filasi ti 112°C. Awọn oniwe-pato walẹ ni D434.2:1.0488. O ti wa ni tiotuka ninu omi, tiotuka ni Organic olomi bi benzene ati oti, insoluble ninu omi tutu, erogba tetrachloride, epo ether ati xylene. Malononitrile ni cyano meji- ati methylene ifaseyin kan, pẹlu iṣẹ ṣiṣe kemikali to lagbara, mejeeji erogba ati awọn ọta nitrogen le ṣe awọn aati afikun; le polymerize. O jẹ majele, o fa awọn rudurudu neurocentric, jẹ ibajẹ ati ibẹjadi.

    Ohun elo:

    (1) Malononitrile jẹ ohun elo aise fun igbaradi ti 2-amino-4,6-dimethoxypyrimidine ati 2-chloro-4,6-dimethoxypyrimidine, eyiti a le lo lati gbe awọn herbicides sulfonylurea gẹgẹbi bensulfuron ati pyrimethamiphosulfuron, ati bẹbẹ lọ. tun ṣee lo lati ṣe iṣelọpọ herbicide diflubenzuron, eyiti a lo ninu iṣelọpọ awọn oogun diuretic ni oogun.

    (2) Organic kolaginni aise ohun elo. Ninu oogun, a lo fun iṣelọpọ ti Vitamin B1, aminopterin, aminobenzyl pteridine ati lẹsẹsẹ awọn oogun pataki miiran. O ni awọn lilo pataki ni awọn dyestuffs, ipakokoropaeku ati awọn ohun elo miiran. O tun le ṣee lo bi ohun jade fun wura. O ti wa ni bayi lo ni China o kun fun isejade ti aminopterin, bensulfuron, 1,4,5,8-naphthalenetetracarboxylic acid ati pyrimidine jara awọn ọja.

    (3) Ti a lo ninu awọn oogun, o jẹ agbedemeji ti aminopterin oogun.

    (4) O le ṣee lo bi awọn ohun elo aise fun iṣelọpọ Organic, awọn agbedemeji elegbogi ati awọn olomi Organic.
