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

2,4-Dinitrophenylhydrazine (CAS: 119-26-6), ihe na-emepụta hydrazine, bụ ihe C-nitro nke bụ phenylhydrazine na-anọchi anya na 2- na 4-ọnọdụ site na nitro otu.Ọ nwere ọrụ dị ka reagent.Ọ bụ akụkụ nke phenylhydrazines na ogige C-nitro.Na aldehydes, mmeghachi omume ketone na-acha ọbara ọbara odo.Ọ na-ere ọkụ ma na-egbu egbu.Ihe mgbawa mgbe akọrọ.Na-emerụ ahụ mgbe ikuru ume, ilo ma ọ bụ na kọntaktị na akpụkpọ ahụ.Ejiri ya dị ka onye na-ahụ maka chromogenic maka mkpebi nke aldehydes na ketones site na fotometry yana maka mkpebi nke aldehydes na ketones site na chromatography oyi akwa.2,4-Dinitrophenylhydrazine ejirila dị ka reagent iji chọpụta ọnụnọ nke aldehydes na ketones na protein carbonyls.Enwere ike iji ya dị ka reagent colorimetric na ọnụọgụ ọnụọgụ nke prednisone.

Dinitrophenylhydrazine na-enwe mmetụta dị nro na ujo na esemokwu;ọ bụ ihe mgbawa na-awụ akpata oyi n'ahụ, yabụ a ga-akpachapụ anya na iji ya.A na-enyekarị ya mmiri mmiri iji belata ihe egwu mgbawa ya.Ọ bụ hydrazine nọchiri anya ya, a na-ejikarị ya anwale nke ọma maka otu carbonyl jikọtara ya na aldehydes na ketones.A pụkwara iji ihe ndị na-emepụta hydrazone mee ihe dị ka ihe akaebe maka njirimara nke ogige mbụ ahụ.Dinitrophenylhydrazine anaghị emeghachi omume na otu ọrụ nwere carbonyl ndị ọzọ dị ka carboxylic acid, amides, na esters.Maka acid carboxylic, amides na esters, enwere nkwụsi ike metụtara resonance dị ka otu ụzọ eletrọn na-emekọrịta ihe na p-orbital nke carbonyl carbon nke na-ebute mmụba n'ime molekul.Nkwụsi ike a ga-efunahụ site na mgbakwunye nke reagent na otu carbonyl.
