2-Chloro-3-bromo-5-methylpyridine (CAS# 17282-03-0) Chiyambi

Ndi organic pawiri ndi mankhwala chilinganizo C8H7BrClN. Zotsatirazi ndikulongosola za chikhalidwe chake, kagwiritsidwe ntchito, kukonzekera ndi chidziwitso cha chitetezo:Chilengedwe:
-Maonekedwe: Nthawi zambiri chikasu mpaka lalanje-chikasu cholimba.
-Kusungunuka: Kusungunuka mu zosungunulira za organic monga ethanol ndi dimethyl sulfoxide, zosasungunuka m'madzi.
- Malo osungunuka: Pafupifupi 70-72 digiri Celsius.
- Kachulukidwe: pafupifupi 1.63 g/mL.
-Kulemera kwa maselo: pafupifupi 231.51g / mol.

Gwiritsani ntchito:
-Nthawi zambiri amagwiritsidwa ntchito ngati wapakatikati pakupanga organic ndipo amagwiritsidwa ntchito kwambiri m'minda yamankhwala, mankhwala ophera tizilombo ndi utoto.
-Zitha kugwiritsidwa ntchito ngati chothandizira, chochepetsera kapena kuchepetsa, ndi zina zotero, zomwe zimakhudzidwa ndi zochitika zosiyanasiyana zamoyo.

Njira: Kukonzekera kwa
-a nthawi zambiri imakhudza zomwe 3-bromo-2-chloropyridine ndi methyl bromide.
-Njira yeniyeni yokonzekera ikhoza kusinthidwa molingana ndi mikhalidwe yoyesera ndi zofunikira.

Zambiri Zachitetezo:
-Imakhala yokhazikika pansi pazikhalidwe zogwirira ntchito, komabe iyenera kugwiritsidwa ntchito mosamala.
- mu ntchito ayenera kusamala kupewa khungu kukhudzana ndi inhalation, ayenera kuvala zoteteza magolovesi, magalasi ndi masks.
-Mukakhudza khungu kapena maso, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita ku chipatala.
- Khalani kutali ndi moto ndi magwero otentha panthawi yosungira, ndipo onetsetsani kuti chidebecho chatsekedwa kuti chiteteze kuphulika kapena kutayikira.
