Daim ntawv thov:

2,4-Dinitrophenylhydrazine (CAS: 119-26-6), hydrazine derivative, yog C-nitro compound uas yog phenylhydrazine hloov ntawm 2- thiab 4-txoj hauj lwm los ntawm nitro pawg.Nws muaj lub luag haujlwm ua reagent.Nws yog ib tug tswv cuab ntawm phenylhydrazines thiab C-nitro compound.Thiab aldehydes, ketone cov tshuaj tiv thaiv liab daj.Nws yog flammable thiab lom.Tshaj tawm thaum qhuav.Teeb meem thaum nqus tau, nqos los yog kov ntawm daim tawv nqaij.Siv los ua tus neeg sawv cev chromogenic rau kev txiav txim siab ntawm aldehydes thiab ketones los ntawm photometry thiab rau kev txiav txim siab ntawm aldehydes thiab ketones los ntawm nyias txheej chromatography.2,4-Dinitrophenylhydrazine tau siv los ua reagent los kuaj pom muaj aldehydes thiab ketones hauv cov protein carbonyls.Nws tuaj yeem siv los ua ib qho xim reagent hauv kev kwv yees ntau ntawm prednisone.

Dinitrophenylhydrazine yog qhov tseem ceeb rau kev poob siab thiab kev sib txhuam;nws yog qhov tawg tawg yog li kev saib xyuas yuav tsum tau ua nrog nws siv.Nws yog feem ntau muab ntub dej kom txo tau nws cov khoom tawg.Nws yog ib qho kev hloov hydrazine, thiab feem ntau yog siv los ntsuas qhov zoo rau carbonyl pawg txuam nrog aldehydes thiab ketones.Cov hydrazone derivatives kuj tseem siv tau los ua pov thawj rau tus kheej ntawm cov khoom qub.Dinitrophenylhydrazine tsis hnov mob nrog lwm cov pa roj carbonyl-muaj cov haujlwm ua haujlwm xws li carboxylic acids, amides, thiab esters.Rau carboxylic acids, amides thiab esters, muaj resonance txuam stability raws li ib leeg-pair ntawm electrons interacts nrog lub p-orbital ntawm carbonyl carbon uas ua rau muaj zog delocalization nyob rau hauv lub molecule.Qhov kev ruaj ntseg no yuav ploj mus los ntawm kev ntxiv cov reagent rau pawg carbonyl.
