3-Amino-2-fluoropyridine (CAS# 1597-33-7)
Ubungozi Nokuphepha
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R36 – Ukucasuka emehlweni I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. |

Isingeniso
Imvelo:
I-3-Amino-2-fluoropyridine iyikristalu eqinile emhlophe enezimpawu zezakhi ze-pyridine. Cishe ayincibiliki emanzini ngezinga lokushisa elivamile, kodwa incibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether, ama-ketone nama-ester. Ine-volatility emaphakathi kanye nephunga elibukhali elinamandla.
Sebenzisa:
I-3-Amino-2-fluoropyridine isetshenziswa kabanzi emkhakheni wezokwelapha, izibulala-zinambuzane kanye nemboni yamakhemikhali. Iyindawo ebalulekile emaphakathi ekuthuthukisweni nasekukhiqizweni kwezinhlanganisela eziningi zebhayoloji, njengemithi kanye nezibulala-zinambuzane. Emkhakheni wezokwelapha, kuvame ukusetshenziswa ekuhlanganiseni ama-antibiotics, izidakamizwa ezilwa namagciwane, izidakamizwa zenhliziyo kanye ne-cerebrovascular. Emkhakheni wezibulala-zinambuzane, ingasetshenziswa njengengxenye ebalulekile yama-insecticides, ama-herbicides nama-ejenti okulawula ukhula. Ngaphezu kwalokho, ngenxa yokuqina kwayo kwamakhemikhali, i-3-Amino-2-fluoropyridine ingasetshenziswa futhi njenge-catalyst kanye ne-solvent ye-organic synthesis reactions.
Indlela:
Ngokuvamile, indlela yokulungiselela ye-3-Amino-2-fluoropyridine ihlanganisa ukuthatha i-chloroacetic acid ne-2-amino sodium fluoride njengezinto zokusetshenziswa, futhi isabela ukukhiqiza i-3-Amino-2-fluoropyridine. Indlela ethile yokulungiselela iyahlukahluka kuye ngezimo nezilinganiso ezisetshenzisiwe.
Ulwazi Lokuphepha:
I-3-Amino-2-fluoropyridine idinga ukunaka izinyathelo zokuphepha ngesikhathi sokusetshenziswa nokugcinwa. Iyacasula futhi kufanele igweme ukuhogela amagesi, uthuli noma umhwamuko kanye nokuthinta isikhumba, amehlo kanye nolwelwesi lwamafinyila. Gqoka amagilavu okuzivikela, izibuko kanye nezingubo zokuzivikela ezifanele ngesikhathi sokusebenza. Uma uhogela umoya ngephutha noma ukuthintana ngephutha, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha. Ngaphezu kwalokho, kufanele igcinwe endaweni epholile, eyomile, enomoya omuhle ngesikhathi sokugcinwa, kude nomlilo kanye nama-oxidants.
