Pyridine-4-boronic acid (CAS# 1692-15-5) sumo
4-Pyridine boronic acid inhengo yehupenyu. Izvi zvinotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye4-pyridine boronic acid:
Hunhu:
- Kuonekwa: 4-pyridine boronic asidhi isina ruvara crystalline yakasimba.
- Solubility: Inonyungudika mumvura uye zvakajairika organic zvinonyungudutsa senge madoro, ether, uye ketoni.
- Kugadzikana: 4-Pyridine boronic acid inogadzikana pakushambidzika kwekamuri, asi kuora kunogona kuitika muhupo hwekushisa kwepamusoro, kudzvinyirirwa kukuru, kana maoxidants ane simba.
Shandisa:
- Catalyst: 4-pyridylboronic acid inogona kushandiswa sechinhu chinokonzeresa mune organic synthesis reactions, seCC bond formation maitiro uye oxidation maitiro.
- Coordination reagent: Iine boron maatomu, uye 4-pyridylboronic acid inogona kushandiswa sekubatanidza reagent yesimbi ions, ichiita basa rinokosha mu catalysis uye mamwe maitiro emakemikari.
Nzira:
- 4-Pyridine boronic acid inogona kuwanikwa nekuita 4-pyridone ne boric acid. Iwo chaiwo maitiro ekuita anozogadziriswa zvinoenderana nemamiriro chaiwo.
Zvekuchengetedza
- 4-Pyridine boronic asidhi izere organic compound, asi zvichiri kudikanwa kutarisira kubata kwakachengeteka. Magirazi ekudzivirira uye magirovhosi anofanira kupfekwa pakushanda.
- Dzivisa kusangana neganda uye inhalation yeguruva. Kana wasangana netsaona neganda, sukurudza pakarepo nemvura yakawanda.
- Panguva yekushandiswa nekuchengetedza, kutarisirwa kunofanira kutorwa kuti usasangana neakasimba oxidants uye yakasimba acids kudzivirira kukonzeresa maitiro ane ngozi.
- Pakurasa tsvina, inofanira kuraswa zvakachengeteka maererano nemitemo yemunharaunda.
