Cuprous bromide Chemical Properties,Uses,Production

Chemical Properties

-80 mesh with 99.999% and 99% purity; white powder(s); cub crystal(s); hygroscopic; turns green to dark blue in sunlight; used as a catalyst for organic reactions [HAW93] [MER06] [STR93] [CER91]


As catalyst for organic reactions.


Copper bromide is also known as cupric bromide, this substance was made by double decomposition when mixing aqueous solutions of copper sulfate and potassium bromide. This greenish blue solution was used as the bleaching step for intensifying collodion and gelatin negatives.

General Description

White powder or crystal. Turns green to dark blue on exposure to sunlight. Sinks and mixes slowly with water.

Air & Water Reactions

Mixes slowly with water.

Reactivity Profile

Cuprous bromide has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

INHALATION: Irritation of upper respiratory tract. EYES: Irritation of conjunctivae. SKIN: Irritation, acne-like rash (usually from prolonged exposure). INGESTION: Vomiting caused by local irritant and astringent action of ionic Cu on stomach and intestines. Pain in mouth, esophagus, and stomach. Inorganic bromides produce depression, psychoses, and mental deterioration.

Purification Methods

Purify it as for cuprous iodide but using aqueous NaBr. [Keller & Wycoff Inorg Synth II 3 1946, Glemser & Sauer in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1006 1965.]
