4-Bromo-2-fluoropyridine (CAS# 128071-98-7)
4-Bromo-2-fluoropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: Madzi opanda mtundu kapena olimba
- Kusungunuka: Imakhala ndi kusungunuka kochepa m'madzi ndipo imasungunuka mu zosungunulira organic monga ether, alcohols ndi ketones.
Gwiritsani ntchito:
- M'munda wa mankhwala ophera tizilombo, atha kugwiritsidwa ntchito kupanga mankhwala ophera tizilombo, fungicides, ndi zina.
- Mu sayansi yazinthu, itha kugwiritsidwa ntchito ngati kalambulabwalo wa zinthu za organic optoelectronic pokonzekera zinthu zokhala ndi zida zapadera za optoelectronic.
Njira:
- Pali njira zambiri kukonzekera 4-bromo-2-fluoropyridine, ndi njira wamba ndi kuchita yankho bromination anachita pa 2-fluoropyridine, ndi sodium bromide kapena sodium bromate anawonjezera monga brominating wothandizila mu anachita.
Zambiri Zachitetezo:
- 4-Bromo-2-fluoropyridine ndi organic pawiri kuti amafuna chitetezo pakugwira.
- Kukhudzana ndi khungu, maso, kapena kupuma mpweya wake kungayambitse mkwiyo ndi kuvulala, ndipo kukhudzana kuyenera kupewedwa.
- Zida zodzitetezera zoyenera monga magalasi oteteza chitetezo, magolovesi, ndi zida zolowera mpweya kunja kwa labotale ziyenera kugwiritsidwa ntchito panthawi yogwira ntchito.
- Chisamaliro chiyenera kutengedwa kuti musakhudzidwe ndi okosijeni, ma asidi, ndi zinthu zina panthawi yosungira ndikugwira kuti mupewe zoopsa.
- Pochigwiritsa ntchito ndikuchitaya, chiyenera kuyendetsedwa motsatira malamulo okhudzana ndi chitetezo ndi ndondomeko zoyendetsera ntchito kuti zitsimikizire chitetezo chaumwini ndi chitetezo cha chilengedwe.
