Pyridinium Tribromide CAS No 39416-48-3 Pyridine Series For Mild Bromination Reactions

Pyridinium tribromide(CAS No:39416-48-3)high quality long production history 

Application

Pyridine tribromide (PHBP) is an excellent brominating agent with certain selectivity, mild reaction conditions, high yield, few side reactions, easy measurement, and easy operation and use. PHBP is a solid complex of bromine and pyridine hydrobromate, which can serve as a source of bromine in the reaction. PHBP is a milder bromination reagent than pure bromine, which can undergo selective bromination and dehydrogenation reactions.

Production methods

Made by reacting pyridine with hydrogen bromide and bromine.
