Hydrobromic Acid (CAS 10035-10-6) is a strong mineral acid with high acidity and reducing properties, supplied as a 48% aqueous solution that appears as a colorless liquid with a strong irritating odour, serving as a Technical Grade reagent for inorganic bromides, organic bromo-compounds, semiconductor etching and battery electrolytes. It is typically supplied as a 48% Aqueous Solution for industrial and laboratory use. Its high reactivity facilitates the cleavage of ethers and the alkylation of specialized chemical intermediates. In the electronics sector, it is used as a high-purity etching agent for semiconductor manufacturing and as an electrolyte in advanced battery systems. It maintains high stability when stored in UV-protected, corrosion-resistant containers.
