Faa'iido leh
Isticmaalka: Pyridinium Tribromide waa reagent loo isticmaalo α-thiocyanation ee ketones waxaana sidoo kale lagu dabaqay isku dhafka wakiilada xannibaya β-adrenergic (sidoo kale loo yaqaan β-blockers) bukaanada wadnuhu shaqaynayo.Brominations-yar-yar, halkaasoo ay aad ugu habboon tahay oo la aqbali karo in la cabbiro oo la isticmaalo marka loo eego bromine element.Pyridine hydrobromide perbromide waxaa loo isticmaalaa sidii reagent brominating ee alfa-bromination iyo alfa-thiocyanation ee ketones, phenols, unsaturated iyo ethers caraf udgoon.Waxaa loo isticmaalaa sida walxo cayriin ah diyaarinta wakiilada xannibaya beta-adrenergic.Intaa waxaa dheer, waxaa loo isticmaalaa sida reagent gorfaynta.
