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

2,4-Dinitrophenylhydrazine (CAS: 119-26-6), o le hydrazine derivative, o le C-nitro compound lea o le phenylhydrazine ua suia i le 2- ma le 4-tulaga e vaega nitro.E i ai sana matafaioi o se reagent.O se sui o le phenylhydrazines ma le C-nitro compound.Ma aldehydes, ketone tali samasama mumu.E mu ma oona.Pa pe a mago.E afaina pe a manava, foloina pe faʻafesoʻotaʻi ma paʻu.Fa'aaogaina e fai ma sui o le chromogenic mo le fuafuaina o aldehydes ma ketones e ala i photometry ma mo le fuafuaina o aldehydes ma ketones e ala ile chromatography layer manifinifi.2,4-Dinitrophenylhydrazine ua faʻaaogaina e avea o se reagent e iloa ai le iai o aldehydes ma ketones i carbonyl protein.E mafai ona fa'aaogaina e fai ma mea fa'asolo lanu i le fua fa'atatau ole prednisone.

O le Dinitrophenylhydrazine e fai si maaleale i le te'i ma le vevesi;ose mea pa te'i e tatau ona fa'aeteete i lona fa'aogaina.E masani ona sapalai susu e fa'aitiitia ai lona lamatiaga papa.O se hydrazine e suitulaga, ma e masani ona faʻaaogaina e suʻesuʻe lelei mo vaega carbonyl e fesoʻotaʻi ma aldehydes ma ketones.E mafai fo'i ona fa'aogaina mea e maua mai ai le hydrazone e fai ma fa'amaoniga e fa'atatau i le fa'asinomaga o le fa'aputu muamua.O le Dinitrophenylhydrazine e le tali atu i isi vaega galue e aofia ai carbonyl e pei ole carboxylic acids, amides, ma esters.Mo acids carboxylic, amides ma esters, o loʻo i ai le mautu e fesoʻotaʻi ma le resonance aʻo fesoʻotaʻi se paʻaga eletonika ma le p-orbital o le carbonyl carbon e mafua ai le faʻateleina o le delocalization i le mole.O lenei mautu o le a leiloa e ala i le faʻaopoopoina o se reagent i le vaega carbonyl.
