2,4-Dinitrophenylhydrazine CAS 119-26-6 Tsafta>98.0% (HPLC)

2,4-Dinitrophenylhydrazine (CAS: 119-26-6), wani nau'i na hydrazine, wani abu ne na C-nitro wanda shine phenylhydrazine wanda aka maye gurbinsa a 2- da 4-matsayi ta ƙungiyoyin nitro.Yana da matsayi a matsayin reagent.Yana da memba na phenylhydrazines da kuma C-nitro fili.Kuma aldehydes, amsawar ketone ja rawaya.Yana da flammable kuma mai guba.Abun fashewa idan ya bushe.Yana da illa idan an shaka, hadiye ko kuma a sadu da fata.An yi amfani da shi azaman wakili na chromogenic don ƙayyade aldehydes da ketones ta hanyar photometry da kuma ƙayyade aldehydes da ketones ta hanyar chromatography na bakin ciki.2,4-Dinitrophenylhydrazine an yi amfani dashi azaman reagent don gano kasancewar aldehydes da ketones a cikin furotin carbonyls.Ana iya amfani da shi azaman reagent mai launi a cikin ƙididdige ƙimar prednisone.

Dinitrophenylhydrazine yana da matukar damuwa ga girgiza da gogayya;abin tashin hankali ne don haka dole ne a kula da amfani da shi.Yawancin lokaci ana ba da shi jika don rage haɗarin fashewar ta.Yana da hydrazine da aka maye gurbinsa, kuma ana amfani dashi sau da yawa don gwadawa da kyau ga ƙungiyoyin carbonyl masu alaƙa da aldehydes da ketones.Hakanan za'a iya amfani da abubuwan da aka samo asali na hydrazone a matsayin shaida ga ainihin fili na asali.Dinitrophenylhydrazine baya amsawa tare da wasu ƙungiyoyin aiki masu ɗauke da carbonyl kamar su carboxylic acid, amides, da esters.Don carboxylic acid, amides da esters, akwai kwanciyar hankali da ke da alaƙa kamar yadda nau'ikan lantarki guda biyu ke hulɗa tare da p-orbital na carbonyl carbon wanda ke haifar da haɓaka haɓakawa a cikin kwayar halitta.Wannan kwanciyar hankali za ta rasa ta hanyar ƙari na reagent zuwa ƙungiyar carbonyl.
