2-Chloro-5-iodopyridine (CAS# 69045-79-0)

Mawu Oyamba

2-Chloro-5-iodopyridine ndi organic pawiri.

2-Chloro-5-iodopyridine ili ndi zinthu zina zofunika. Ndi mankhwala onunkhira omwe ali ndi magulu ogwira ntchito monga ma alcohols ndi amines, omwe ali ndi electrophilicity yamphamvu. Kachiwiri, imakhala ndi kusungunuka kwakukulu komanso kuthamanga kwa mpweya wochepa, ndipo imatha kukhala yolimba kapena yamadzimadzi kutentha.

Pagululi ali ndi ntchito zosiyanasiyana m'madera angapo. Nthawi zambiri amagwiritsidwa ntchito ngati reagent kapena chothandizira mu organic synthesis reactions, mwachitsanzo ngati chothandizira cha esterification. Itha kugwiritsidwanso ntchito popanga mankhwala ophera tizilombo, inki, ndi utoto.

Pali njira zingapo zokonzekera 2-chloro-5-iodopyridine. Njira yodziwika bwino ndikuchita 2-chloro-5-aminopyridine ndi thionyl iodide kapena haidrojeni iodide kuti apange pawiri momwe zimachitikira. Itha kukonzedwanso ndi ayodini wa 2-chloro-5-bromopyridine.

Zambiri zachitetezo: 2-chloro-5-iodopyridine ndi organic pawiri yokhala ndi zoopsa zina. Pogwira ntchito, njira zotetezera monga kuvala magolovesi oteteza, magalasi, ndi zovala zodzitetezera ndizofunikira. Iyenera kugwiritsidwa ntchito potulutsa mpweya wabwino ndikupewa kupumira, kuyamwa, kapena kukhudzana ndi khungu. Ngati mwakhudzana mwangozi kapena pokoka mpweya, pitani kuchipatala msanga.
