Pyridinium tribromide Chemical Properties,Uses,Production

Chemical Properties

red crystals

Uses

Pyridinium Tribromide is a reagent used in the α-thiocyanation of ketones and has also been applied to the synthesis of β-adrenergic blocking agents (also known as β-blockers) for patients with heart failure.

Uses

In small-scale brominations, where it is much more convenient and agreeable to measure and use than elemental bromine.

Purification Methods

It is a very good brominating agent-liberating one mol of Br2. Purify it by recrystallisation from glacial acetic acid (33g from 100mL of AcOH) to give orange-red crystals.
