I-2,4-Dinitrophenylhydrazine (i-CAS: i-119-26-6), i-derivative ye-hydrazine, i-C-nitro compound ebizwa ngokuba yi-phenylhydrazine efakwe kwi-2- kunye ne-4-izikhundla ngamaqela e-nitro.Inendima njenge-reagent.Lilungu le-phenylhydrazines kunye ne-C-nitro compound.Kwaye aldehydes, ketone reaction ebomvu tyheli.Iyatsha kwaye inetyhefu.Iziqhushumbisi xa zomile.Kuyingozi xa uphefumlelwa, uginya okanye udibana nesikhumba.Isetyenziswe njenge-agent ye-chromogenic yokumisela i-aldehydes kunye ne-ketones nge-photometry kunye nokumisela i-aldehydes kunye ne-ketones nge-chromatography encinci.I-2,4-Dinitrophenylhydrazine isetyenziswe njenge-reagent ukubona ubukho be-aldehydes kunye ne-ketones kwiiprotheni carbonyls.Isenokusetyenziswa njenge-reagent colorimetric kuqikelelo lobungakanani be-prednisone.
I-Dinitrophenylhydrazine inovelwano ngokuthelekiswa nokothuka kunye nokukhuhlana;sisiqhushumbisi esothusayo ngoko ke kufuneka kuthathelwe ingqalelo ukusetyenziswa kwayo.Idla ngokubonelelwa ngokumanzi ukunciphisa ubungozi bayo bokuqhushumba.I-hydrazine efakwe endaweni, kwaye isoloko isetyenziselwa ukuvavanya ngokusemgangathweni amaqela e-carbonyl ahambelana ne-aldehydes kunye neetoni.I-hydrazone derivatives inokusetyenziswa njengobungqina obubhekiselele kubunikazi bekhompawundi yokuqala.I-Dinitrophenylhydrazine ayifuni kunye namanye amaqela asebenzayo aqukethe i-carbonyl efana ne-carboxylic acids, i-amides, kunye ne-esters.Kwi-carboxylic acids, i-amides kunye ne-esters, kukho ukuzinza okuhambelana ne-resonance njengoko isibini esisodwa se-electron sisebenzisana ne-p-orbital ye-carbonyl carbon ekhokelela ekwandeni kwe-delocalization kwi-molecule.Oku kuzinza kuya kulahleka ngokongezwa kwe-reagent kwiqela le-carbonyl.
