2-Bromo-5-amino-4-picolin (CAS# 156118-16-0)

Ama-ID e-UN	I-UN2811
I-Hazard Class	6.1

I-2-BROMO-5-AMINO-4-PICOLINE iyinhlanganisela yezinto eziphilayo. Ifomula yayo yamakhemikhali ithi C6H7BrN2.Properties: 2-BROMO-5-AMINO-4-PICOLINE iyikristalu ephuzi emhlophe kuya kokuphaphathekile enephunga eliyingqayizivele. Iyancibilika otshwaleni nasezincibilikisini zeKetone ekamelweni lokushisa, inyibilika kancane emanzini.Izisetshenziswa: 2-BROMO-5-AMINO-4-PICOLINE ivame ukusetshenziswa njenge-catalyst ekuphenduleni kwe-organic synthesis. Ingasetshenziswa njenge-reagent esikhundleni se-amino ukuze kuhlanganiswe ezinye izinhlanganisela, njengezidakamizwa, odayi kanye nezibulala-zinambuzane. Ngaphezu kwalokho, ingasetshenziswa futhi njenge-ligand ye-ion yensimbi.

Indlela Yokulungiselela: I-2-BROMO-5-AMINO-4-PICOLINE ingalungiswa ngezindlela ezihlukahlukene. Indlela eyodwa evamile iwukusabela i-4-methyl-2-pyridinamine nge-methyl bromide ngaphansi kwezimo eziyisisekelo. Ngemuva kokusabela, umkhiqizo uhlanzwa nge-crystallization noma ezinye izindlela.

Ulwazi lokuphepha: I-2-BROMO-5-AMINO-4-PICOLINE inobuthi obuphansi, kodwa kusadingeka ukuthi unake ukusebenza okuphephile. Gqoka amagilavu ​​okuzivikela afanelekile, izibuko, nezingubo lapho usebenzisa noma uphethe inhlanganisela. Ngesikhathi esifanayo, kufanele isetshenziswe endaweni engenawo umoya ukuze igweme ukuhogela uthuli noma umhwamuko wayo. Uma uthathwe ngephutha noma uhogelwe ngephutha, funa usizo lwezempilo ngokushesha.
