Difluoromethane ba shi da launi, iskar gas mai ƙonewa tare da ɗan ƙaramin ƙamshi mai kama da ether. Ana jigilar shi azaman iskar gas a ƙarƙashin tururinsa. Difluoromethane, wanda ake kira difluoromethylene, HFC-32 Methylene Fluoride ko R-32, wani fili ne na kwayoyin halitta na dihalogenoalkane iri-iri. Yana da tsari na CH2F2. Yana da iskar gas mara launi a cikin yanayi na yanayi kuma yana da dan kadan mai narkewa a cikin ruwa, tare da babban kwanciyar hankali na thermal.Saboda ƙananan narkewa da tafasa, (-136.0 ° C da -51.6 ° C bi da bi) lamba tare da wannan fili na iya haifar da frostbite.Difluoromethane da aka saba amfani da endothermic matakai kamar refrigeration ko iska kwandishan.Difluoromethane da farko hada ta hanyar tsari matakai, da dauki na dichloromethane da hydrogen fluoride (HF), a cikin ruwa lokaci ta amfani da SbCl5 a matsayin mai kara kuzari.Difluoromethane yawanci amfani da a matsayin mai kashe wuta saboda iyawar da za ta iya aiwatar da hanyoyin endothermic.Sauran amfani da difluoromethane sun haɗa da yin amfani da shi azaman masu haɓaka iska, masu busawa, da sauran ƙarfi.
