● Kev Siv: Pyridinium Tribromide yog ib qho reagent siv nyob rau hauv α-thiocyanation ntawm ketones thiab kuj tau siv rau cov synthesis ntawm β-adrenergic blocking agents (tseem hu ua β-blockers) rau cov neeg mob plawv tsis ua hauj lwm.Hauv me me brominations, qhov twg nws yooj yim dua thiab pom zoo rau kev ntsuas thiab siv dua li bromine elemental.Pyridine hydrobromide perbromide yog siv los ua brominating reagent hauv alfa-bromination thiab alfa-thiocyanation ntawm ketones, phenols, unsaturated thiab aromatic ethers.Nws yog siv los ua raw khoom hauv kev npaj ntawm beta-adrenergic blocking agents.Tsis tas li ntawd, nws yog siv los ua ib qho analytical reagent.
