2,4-Dinitrophenylhydrazine (CAS: 119-26-6), chotengera cha hydrazine, ndi C-nitro mankhwala omwe ali phenylhydrazine m'malo mwa 2- ndi 4-malo ndi magulu a nitro.Ili ndi ntchito ngati reagent.Ndi membala wa phenylhydrazines ndi C-nitro pawiri.Ndipo aldehydes, ketone reaction red yellow.Ndi yoyaka ndi poizoni.Zophulika zikauma.Zowopsa mukakokedwa, kumeza kapena kukhudza khungu.Amagwiritsidwa ntchito ngati chromogenic wothandizira kutsimikiza kwa aldehydes ndi ketoni ndi photometry komanso kudziwa ma aldehydes ndi ma ketoni ndi chromatography yopyapyala.2,4-Dinitrophenylhydrazine yakhala ikugwiritsidwa ntchito ngati reagent kuti azindikire kukhalapo kwa aldehydes ndi ketoni mu mapuloteni carbonyls.Itha kugwiritsidwa ntchito ngati colorimetric reagent mu kuchuluka kwa prednisone.
Dinitrophenylhydrazine imakhudzidwa kwambiri ndi kugwedezeka ndi kukangana;ndi kuphulika kochititsa mantha kotero kusamala kuyenera kutengedwa ndi kugwiritsidwa ntchito kwake.Nthawi zambiri amaperekedwa chonyowa kuti achepetse ngozi yake yophulika.Ndiwolowa m'malo mwa hydrazine, ndipo nthawi zambiri amagwiritsidwa ntchito kuyesa moyenera magulu a carbonyl okhudzana ndi aldehydes ndi ketoni.Zotengera za hydrazone zitha kugwiritsidwanso ntchito ngati umboni wotsimikizira zomwe zidayambira.Dinitrophenylhydrazine sagwirizana ndi magulu ena ogwira ntchito omwe ali ndi carbonyl monga carboxylic acids, amides, ndi esters.Kwa ma carboxylic acid, amides ndi esters, pali kukhazikika komwe kumalumikizidwa ndi kukhazikika komwe ma elekitironi amalumikizana ndi p-orbital ya carbonyl kaboni zomwe zimapangitsa kuti ma molekyulu achuluke.Kukhazikika kumeneku kungatayike powonjezerapo reagent ku gulu la carbonyl.
