Product Overview
Cuprous Bromide, systematically known as Copper(I) Bromide, represents a vital inorganic compound within the modern chemical supply chain. Identified by CAS number 7787-70-4, this substance is characterized by its white cubic crystal structure or fine powder appearance. While stable under inert conditions, it is important to note that the material may gradually oxidize to a green coloration when exposed to atmospheric oxygen over extended periods. Our production facilities utilize advanced synthesis routes to deliver high industrial purity, ensuring consistent performance for downstream applications.
With a molecular formula of CuBr and a molecular weight of 143.45, this compound exhibits specific solubility characteristics, being soluble in hydrobromic acid, hydrochloric acid, nitric acid, and ammonia. However, it decomposes in hot water and remains insoluble in acetone, acetic acid, and boiling concentrated sulfuric acid. These physical and chemical properties make it a specialized choice for specific reaction environments where precise control over reactivity is required.
