quality
Data yakavimbika
Red crystalline powder. Nzvimbo yekunyunguduka inenge 200 ° C. Zvishoma soluble mumvura, ethanol, soluble mu acid. Kuputika kunogona kuitika kana kwakafumurwa nekupisa, kubata nemurazvo wakavhurika, kupisa kwakanyanya, kukweshera, kuzunguzika, uye kukanganisa. Kana yapiswa, inoburitsa utsi hune chepfu uye hunoshatirisa. Kusanganiswa neoxidants kunogona kugadzira misanganiswa inoputika.

Nzira
Data yakavimbika
Hydrazine sulfate yakaturikwa mumvura inopisa, potassium acetate yakawedzerwa, yakanyoroveswa mushure mekuvira, ethanol yakawedzerwa, yakaoma yakasvibiswa kunze, uye filtrate yakashambidzwa ne ethanol. 2,4-= nitrophenyl ethanol yakawedzerwa kune iri pamusoro pe hydrazine solution, uye 2,4-= nitrophenylhydrazine yakawanikwa nekutsvaira, kushambidza, kuomesa, uye filtrate concentration.

use
Data yakavimbika
Iyo chromogenic reagent yekugadzika kwe aldehydes uye ketoni neyakaonda layer chromatography. Inoshandiswa se ultraviolet derivatization reagent ye aldehydes uye ketoni mune organic synthesis uye zvinoputika kugadzira.

kuchengeteka
Data yakavimbika
gonzo remuromo LDso: 654mg/kg. Inoshungurudza maziso neganda. Inonzwisa ganda. Ichi chigadzirwa chinopinzwa mumuviri, izvo zvinogona kukonzera methemoglobinemia uye cyanosis. Chengetedza muimba yekuchengetera inotonhorera, ine mhepo. Ramba kure nemoto nekupisa. Iyo tembiricha yekuchengetera zvinhu haifanire kudarika 30 ° C. Dzivirira kubva kuzuva rakananga. Chengetedza mudziyo wakavharwa zvakasimba. Nezvikonzero zvekuchengetedza, inowanzonyoroveswa uye kupfuudzwa isina isingasviki 25% mvura panguva yekuchengetedza uye yekufambisa. Inofanira kuchengetwa zvakasiyana kubva kune oxidants uye acids. Usasanganise kuchengetedza uye chekufambisa.
