Ko te 2,4-Dinitrophenylhydrazine (CAS: 119-26-6), he hydrazine derivative, he pūhui C-nitro ko te phenylhydrazine te whakakapi i te 2- me te 4-turanga e nga roopu nitro.He mahi hei reagent.He mema o te phenylhydrazines me te pūhui C-nitro.Me te aldehydes, te tauhohenga ketone he whero kowhai.He mura me te paitini.Pahū ina maroke.He kino ki te hongi, ka horomia, ka pa ranei ki te kiri.Ka whakamahia hei kaihoko chromogenic mo te whakatau i nga aldehydes me nga ketones ma te whakaahua me te whakatau i nga aldehydes me nga ketones ma te chromatography paparanga angiangi.Kua whakamahia te 2,4-Dinitrophenylhydrazine hei reagent ki te kite i te noho o nga aldehydes me nga ketones i roto i nga waroora pūmua.Ka taea te whakamahi hei reagent colorimetric i roto i te whakatau tata ine o prednisone.
Ko te Dinitrophenylhydrazine he ahua ngawari ki te wiri me te waku;he pahū ohorere no reira me tupato ki te whakamahi.I te nuinga o te wa ka tukuna he makuku hei whakaiti i tana morearea pahū.He hydrazine whakakapi, a he maha nga wa e whakamahia ana hei whakamatautau tohu mo nga roopu waro e pa ana ki nga aldehydes me nga ketones.Ka taea hoki te whakamahi i nga hua o te hydrazone hei taunakitanga mo te tuakiri o te puhui taketake.Ko te Dinitrophenylhydrazine e kore e tauhohe ki etahi atu roopu mahi waro-ira penei i te waikawa carboxylic, amides, me te esters.Mo nga waikawa carboxylic, amides me te esters, he taunga e pa ana ki te resonance i te mea ko te takirua takitahi o nga irahiko e pahekoheko ana ki te p-orbital o te waro waro waro, ka nui ake te wetewete i roto i te ngota.Ka ngaro tenei pumau ma te taapiri i tetahi reagent ki te roopu waro.
