Ethyl 2, ndi organic pawiri ndi mankhwala formula C7H5Cl2NO2. Ndi madzi opanda mtundu mpaka achikasu komanso onunkhira.

Pagululi nthawi zambiri amagwiritsidwa ntchito ngati zinthu zapakatikati komanso zopangira, ndipo ali ndi ntchito zambiri pakuphatikiza organic. Nthawi zambiri amagwiritsidwa ntchito pokonzekera mankhwala ophera tizilombo, mankhwala ndi utoto ndi mankhwala ena. Kuphatikiza apo, itha kugwiritsidwanso ntchito pophunzira momwe amachitira ndi mankhwala a ethyl nicotinate.

Njira yokonzekera ethyl 2 ndikuchita 2,6-dichloropyridine-3-formic acid ndi ethanol, nthawi zambiri pansi pa acidic.

ethyl 2, pali chiopsezo china chachitetezo. Ndi mankhwala opweteka omwe angayambitse kupsa mtima kwa maso, khungu ndi kupuma. Pogwira ntchito, valani zida zotetezera kupuma, magalasi otetezera, magolovesi otetezera ndi zida zotetezera mapazi. Kuphatikiza apo, ilinso ndi ngozi yamoto, iyenera kukhala kutali ndi moto wotseguka komanso kutentha kwakukulu.

Pazifukwa zachitetezo, mukamagwiritsa ntchito ethyl 2, tsatirani njira zolondola za labotale ndikugwira ntchito pamalo opumira bwino.

Zam'mbuyo: Tetrapropyl ammonium chloride (CAS# 5810-42-4)

Ena: D-Glutamine (CAS # 5959-95-5)
