Bromine mononitrate is an inorganic compound, derived from bromine and nitric acid with the chemical formula BrNO3. The compound is a yellow liquid, decomposes at temperatures above 0 °C.[1]

This compounds is extremely reactive due to its intrinsic instability, which makes handling and synthesis challenging. Because of its explosive potential and corrosive character, this substance is mostly used for study in restricted laboratory settings. About its particular characteristics and uses outside of its use as a chemical research subject, not much is known.

Synthesis

Bromine nitrate can be prepared by several methods:

1. Reaction of silver nitrate on an alcoholic solution of bromine:

Br2 + AgNO3 → BrNO3 + AgBr

2. Reaction of bromine chloride with chlorine nitrate at low temperatures:

BrCl + ClNO3 → BrNO3 + Cl2

Physical properties

Bromine mononitrate forms an unstable yellow liquid that decomposes at temperatures above 0 °C.

The molecule has the structure BrONO2.[2][3]

The compound is easily soluble in trichlorofluoromethane and carbon tetrachloride.

Applications

Bromine nitrate plays a role in tropospheric chemistry as it reacts with sulfuric acid.[4][5]
