2,4-Dinitrophenylhydrazine(CAS#119-26-6) folasia

uiga lelei
Fa'amaumauga fa'atuatuaina
Pa'u tioata mumu. O le mea e liusuavai ai e tusa ma le 200°C. Solu teisi i le vai, ethanol, soluble i le acid. E mafai ona tupu le pa pe a faʻaalia i le vevela, faʻafesoʻotaʻi ma le mumu matala, vevela maualuga, feteʻenaʻiga, vibration, ma le aʻafiaga. A mu, e fa'asu'u mai ai le asu o'ona ma fa'aita. O le fa'afefiloi ma mea fa'ama'i e mafai ona fa'atupu fa'afefiloi pa.

Metotia
Fa'amaumauga fa'atuatuaina
O le hydrazine sulfate sa faʻamalolo i totonu o le vai vevela, faʻapipiʻi le potassium acetate, faʻamalo pe a uma ona faʻapuna, faʻaopopo le ethanol, faʻamaʻaʻaʻa ese, ma fufulu le filtrate i le ethanol. 2,4-= nitrophenyl ethanol na faʻaopoopoina i le vaifofo o le hydrazine o loʻo i luga, ma le 2,4-= nitrophenylhydrazine na maua e ala i le faʻamamaina, fufuluina, faʻamago, ma le faʻaogaina o le filtrate.

fa'aoga
Fa'amaumauga fa'atuatuaina
O se chromogenic reagent mo le fuafuaina o aldehydes ma ketones e ala ile chromatography layer manifinifi. O lo'o fa'aaogaina e fai ma sui o le ultraviolet derivatization reagent mo aldehydes ma ketones i le fa'aogaina o meaola ma le gaosiga o mea pāpā.

saogalemu
Fa'amaumauga fa'atuatuaina
isumu tuugutu LDso: 654mg/kg. E fa'afefe i mata ma le pa'u. E ma'ale'ale i le pa'u. O lenei oloa e mitiia i totonu o le tino, lea e mafai ona mafua ai le methemoglobinemia ma le cyanosis. Teu i totonu o se faleteuoloa malulu ma ea. Taofi mai le afi ma le vevela. Ole vevela ole faleteuoloa e le tatau ona sili atu ile 30°C. Puipui mai le susulu o le la. Taofi mau le koneteina. Mo mafua'aga saogalemu, e masani ona fa'asusu ma fa'afefe i lalo ole 25% vai ile taimi e teu ai ma felauaiga. E tatau ona teu ese mai oxidants ma acids. Aua le faʻafefiloi le teuina ma le felauaiga.
