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

2,4-Dinitrophenylhydrazine (CAS: 119-26-6), derivative hydrazine, waa xarun C-nitro ah oo ah phenylhydrazine oo lagu beddelay 2- iyo 4-boosyada kooxaha nitro.Waxay leedahay door sida reagent.Waa xubin ka mid ah phenylhydrazines iyo xarun C-nitro ah.Iyo aldehydes, falcelinta ketone ee casaanka ah ee jaalaha ah.Waa guban karta waana sun.Qarax marka uu qallalo.Waxyeelo leh marka la nuugo, la liqo ama maqaarka taabto.Loo isticmaalo sidii wakiilka chromogenic si loo go'aamiyo aldehydes iyo ketones by photometry iyo go'aaminta aldehydes iyo ketones by chromatography lakabka khafiif ah.2,4-Dinitrophenylhydrazine ayaa loo isticmaalay sidii reagent si loo ogaado joogitaanka aldehydes iyo ketones ee borotiinka carbonyls.Waxa laga yaabaa in loo isticmaalo sidii reagent colorimetric ah marka la eego qiyaasta qiyaasta prednisone.

Dinitrophenylhydrazine waa mid aad u xasaasi u ah shoogga iyo jahwareerka;waa qarax naxdin leh markaa waa in laga taxadaraa isticmaalkeeda.Badanaa waxaa la keenaa qoyan si loo yareeyo khatarteeda qarxa.Waa hydrazine la beddelay, waxaana badanaa loo isticmaalaa in si tayo leh loogu tijaabiyo kooxaha karbonyl ee la xidhiidha aldehyde iyo ketones.Soosaarayaasha hydrazone sidoo kale waxaa loo isticmaali karaa caddayn ahaan aqoonsiga xarunta asalka ah.Dinitrophenylhydrazine kama falceliso kooxaha kale ee kaarboonyl-ku jira ee shaqeeya sida karboxilic acids, amides, iyo esters.Asiidhyada karboksilic, amides iyo esters, waxaa jira xasillooni la xiriirta resonance sida lammaane-kaliya ee elektarooniga ah ayaa la falgala p-orbital ee kaarboonka kaarboonyl taasoo keentay hoos u dhac ku yimid molecule-ka.Xasiloonidan waxa ay luminaysaa marka lagu daro reagent kooxda karbonyl.
