5-bromo-2-pyridinecarboxylic acid ethyl ester (CAS# 77199-09-8)
Mawu Oyamba
Ethyl 5-bromo-2-pyrimidincarboxylate ndi organic pawiri. Izi ndi zina zokhudza katundu, ntchito, njira zokonzekera ndi chitetezo cha pawiri:
Ubwino:
- Maonekedwe: Ethyl 5-bromo-2-pyrimidincarboxylate ndi madzi achikasu otumbululuka.
- Kusungunuka: Kutha kusungunuka mu zosungunulira za organic monga ethanol ndi methylene chloride, koma sikusungunuka m'madzi.
Gwiritsani ntchito:
Ethyl 5-bromo-2-pyrimidincarboxylic acid nthawi zambiri amagwiritsidwa ntchito ngati gawo lapakati pakupanga organic.
- Itha kugwiritsidwanso ntchito ngati chowunikira m'malo ofufuza.
Njira:
- The synthesis wa ethyl 5-bromo-2-pyrimidincarboxylic asidi akhoza analandira ndi esterification wa asidi bromobenzoic pa pyrimidine mphete.
- Pochita izi, p-bromobenzoic acid ndi isopropyl carbonate amayamba kuchitapo kanthu kuti apange isopropyl p-bromobenzoate, ndiyeno powonjezera pyrimidine, kutentha kutentha koyenera komanso kuchitapo kanthu kwa nthawi, 5-bromo-2-yomaliza - pyrimidincarboxylate ethyl ester amapezeka.
- Samalirani momwe kutentha kumachitikira, nthawi yochitira, komanso kuchuluka kwa ma reactants pokonzekera kuti mupeze chinthu chokhala ndi zokolola zambiri komanso chiyero.
Zambiri Zachitetezo:
- Ethyl 5-bromo-2-pyrimidincarboxylate ndi organic pawiri ndipo amatha kuyaka.
- Tsatirani njira zodzitetezera m'ma labotale ndikuvala zida zodzitetezera zoyenera monga magolovesi ndi magalasi mukamagwiritsa ntchito ndikugwira.
- Pewani kukhudza khungu, maso, ndi mpweya.
- Mukakhudzana mwangozi, muzimutsuka ndi madzi ambiri pamalo okhudzidwawo ndikupita kuchipatala.
