Description

General description

Hydrobromic acid solution (HBr) is a clear, yellow or brown colored liquid. Its reaction with K has been studied by a molecular beam technique.

Application

Hydrobromic acid solution may be used for the demethylation of 3,4-dimethoxy-6-bromonitrobenzene. Along with paraldehyde, it forms an efficient bromomethylating agent for benzene derivatives.

Hydrobromic acid solution may be used to infrared spectroscopic analysis of degree of N-deacetylation of chitosan.
