Guryaha

Dareere aan midab lahayn oo guban kara oo leh ur yar oo ammonia ah .mp-61°C, bp152.8°C, barta iftiinka 57.7°C, tusmada refractive 1.427-1.429, cufnaanta (20°C) 0.9487g/ml, oo lagu qasi karo biyo, ether, ester, ketone, hydrocarbon chlorine iyo benzene hydrocarbon, hygroscopic.

Isticmaalka

DMF waa walax muhiim ah oo dabiici ah iyo dareere wanaagsan. Waxaa loo isticmaalaa dareere ahaan maqaar iyo faybar kiimiko ah oo dadku sameeyo, sidoo kale waxaa loo isticmaalaa walxo lagu sameeyo sunta cayayaanka ee waxtarka sare leh iyo sunta yar, sida nuugista gaaska si loo kala saaro loona nadiifiyo gaaska warshadaha kiimikada batroolka, sida walax ka kooban sulfadiazine, cortisone iyo Vitamin B6 warshadaha dawooyinka, iyo sidoo kale wakiil hagaajin ah falanqaynta marxaladda uumiga.

Baakaynta iyo kaydinta

200L oo foosto balaastig ah ama baaldi bir ah oo balaastig ah. Si adag ayaa loo xiray si loo kaydiyo, looga hortago daadashada, laga fogaado roobka, iftiinka qorraxda, si adag u mamnuuc in la xoqo oo la xoqo, meel ka fog dabka iyo meesha kulaylka laga helo, lagu kaydiyo meelo qabow oo hawo leh.
