Cuprous Bromide

Superior High-Temperature Stability – Featuring a high melting point of 498 °C and boiling point of 1345 °C, cuprous bromide maintains stable structural and chemical properties under high-temperature working conditions, adapting to rigorous thermal reaction processes.

Excellent Complexing & Compatibility – It can readily form stable complexes with hydrochloric acid, hydrobromic acid and ammonia solution. Its flexible chemical coordination ability makes it highly adaptable for diverse organic synthesis systems.

Controllable Solubility Characteristics – Sparingly soluble in cold water while decomposing only in hot water or nitric acid, with insolubility in concentrated sulfuric acid and propyl acetate. Such selective solubility enables precise reaction control for lab and industrial usage.

High-Purity Crystalline Texture – Presented as uniform white powder or cubic crystals with stable batch consistency. Its pure morphology ensures easy handling and reliable performance for precision chemical applications.

Product Description
