5-Bromo-4-methyl-pyridine-2-carboxylic acid (CAS# 886365-02-2)

Isingeniso

Kuyinhlanganisela ye-organic ifomula yayo yamakhemikhali ithi C7H6BrNO2.

Izici ze-compound zihlanganisa:

-Ukubukeka: Ayinambala ikristalu ephuzi noma impushana ekhanyayo

-Indawo yokuncibilika: 63-66°C

-Indawo yokubilisa: 250-252°C

-Ukuminyana: 1.65g/cm3

Ivamise ukusetshenziswa njengendawo ephakathi ekuhlanganiseni ezinye izinto eziphilayo. Inezinhlelo zokusebenza ezibalulekile emkhakheni wezokwelapha futhi ingasetshenziswa ukuhlanganisa imikhiqizo yama-molecule ezidakamizwa ezithile. Ngaphezu kwalokho, iphinde ibe yi-synthetic intermediate yama-antibacterial agents aphumelela kakhulu. Ezinye izinhlelo ezingasetshenziswa zihlanganisa ukusetshenziswa njengama-catalyst, odayi be-photosensitizing, nezibulala-zinambuzane.

Indlela yokulungisa i-pyridine isekelwe ngokuyinhloko ku-bromination ye-4-methylpyridine kanye ne-sodium cyanide ku-5-bromo-4-methylpyridine, bese isabela nge-rhenium trioxide ku-dichloromethane ukuze kukhiqizwe umkhiqizo ohlosiwe.

Mayelana nolwazi lokuphepha, inobuthi obuthile nokucasuka. Sicela unake izinto ezilandelayo uma uyisebenzisa:

-Gwema ukuhogela uthuli, intuthu namagesi ukuze uvimbele ukuthintana nesikhumba namehlo.

-Gqoka izinto zokuzivikela ezifanele ngesikhathi sokusetshenziswa, njengezingilazi zokuzivikela zamakhemikhali, amagilavu ​​okuzivikela kanye nezingubo zokuzivikela.

-Kufanele isetshenziswe endaweni engenawo umoya futhi igcine indawo yokusebenza ihlanzekile.

-Isitoreji kufanele sigcinwe endaweni eyomile, epholile, kude nomlilo kanye nama-oxidizing agents.

Lapho usebenzisa insimbi, sicela ulandele ukusebenza okufanele nemithethonqubo yokuphepha, futhi uhlole ubungozi bayo nezingozi ezingaba khona ngokuya ngesimo esithile.
