Zoo siv
● Siv: Pyridinium Tribromide yog qhov reagent siv nyob rau hauv cov khoom siv hauv tsev pheeb suab (tseem hu ua cov neeg mob uas muaj lub siab tsis ua haujlwm. Hauv cov nplai me me-nplai ua rau muaj qhov chaw yooj yim dua, qhov chaw yooj yim dua thiab pom zoo los ntsuas thiab siv tshaj li lub cim bromine. Pyrobromide pyromide yog siv los ua ib tug brominating reagent nyob rau hauv alfa-bromination thiab alfa-thiocyanation ntawm ketones, phenols, tsis muaj kev ua tsis tau zoo. Nws yog siv los ua cov khoom siv raw hauv kev npaj ntawm beta-adrengic thaiv cov neeg sawv cev. Tsis tas li ntawd, nws yog siv los ua qhov ntsuas kev ntsuas.
