CAS Registry Number: 39416-48-3
CAS Name: Hydrogen tribromide compd with pyridine (1:1)
Molecular Formula: C5H6Br3N
Molecular Weight: 319.82
Percent Composition: C 18.78%, H 1.89%, Br 74.95%, N 4.38%
Line Formula: C5H5N+HBr3-
Literature References: Prepd from pyridine, hydrobromic acid, and bromine: L. F. Fieser, M. Fieser, Reagents for Organic Chemistry vol. 1 (John Wiley, New York, 1967) p 967.
Properties: Orange-needles from acetic acid. Odorless. Nonvolatile. Sparingly sol in acetic acid. Dissociates in the presence of a bromine acceptor, such as an alkene, to liberate one mole of bromine.
Use: In small-scale brominations, where it is much more convenient and agreeable to measure and use than elemental bromine.
