3-Bromoisonicotinic acid (CAS # 13959-02-9) Taw qhia
3-Bromoisonitic acid, tshuaj formula C5H5BrO2, yog cov organic compound. Hauv qab no yog cov lus piav qhia ntawm cov khoom, kev siv, kev npaj thiab kev nyab xeeb ntawm 3-bromoisoniacin:
Xwm:
-Cov tsos mob: 3-Bromoisonicotinic acid yog dawb los yog lub teeb daj crystals nrog ib tug tshwj xeeb tsw.
-Solubility: 3-Bromoisonicotinic acid yog soluble hauv dej, ethanol thiab ether.
Siv:
-Pharmaceutical teb: 3-Bromoisoniacin yog ib qho tseem ceeb nruab nrab uas yuav siv tau los ua ke cov tshuaj thiab bioactive molecules.
-Kev sim cev nqaij daim tawv thiab tshuaj lom neeg: 3-bromoisonicotinic acid tuaj yeem siv los ua cov khoom siv hauv chav kuaj, xws li pH ntsuas thiab cov tshuaj ua kom yooj yim.
Txoj Kev Npaj:
-Cov synthesis ntawm 3-bromoisonicotinic acid feem ntau yog tau los ntawm bromination ntawm isonicotinic acid. Bromine thiab isonicotinic acid tuaj yeem raug cuam tshuam ncaj qha raws li qhov tsim nyog cov tshuaj tiv thaiv kom muab 3-bromoisonicotinic acid.
Cov ntaub ntawv kev nyab xeeb:
-3-Bromoisonitic acid yog khaus thiab muaj peev xwm ua xua. Hnav cov cuab yeej tiv thaiv tsim nyog thaum lub sijhawm ua haujlwm kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
-Thaum khaws cia thiab tuav 3-bromoisonitic acid, kom deb ntawm qhov hluav taws kub thiab oxidizing cov neeg ua haujlwm kom tsis txhob muaj pa phem thiab vapors.
-Yog tias koj nqus tau los yog haus 3-bromoisinicotinic acid, nrhiav kev pab kho mob tam sim ntawd thiab muab cov ntsiab lus tshuaj rau koj tus kws kho mob kom kho.
