Hydrogen Bromide
Hydrogen bromide is a colorless gas or fuming liquid (aqueous solution) with the formula HBr and molecular weight 80.91 g/mol. It has a density of 1.49 g/cm³ (liquid), boiling point -66.8°C, melting point -86.9°C, and is highly soluble in water (forming hydrobromic acid, up to 68% at 25°C). It has a sharp, irritating odor and is produced by reaction of bromine with hydrogen or hydrolysis of phosphorus tribromide; strong acid used in synthesis.
Hydrogen Bromide
Used in the production of bromides for pharmaceuticals and agrochemicals; as a catalyst in alkylation reactions; in petroleum industry for hydrocracking; in organic synthesis for addition to alkenes; in analytical chemistry as reagent; in electronics for etching.
Highly corrosive, causes severe burns to skin, eyes, and lungs; toxic by inhalation leading to pulmonary edema. Reacts exothermically with bases and metals; non-flammable but supports combustion; use PPE, ventilate; Hazard Class 8 (corrosive) and 2.3 (toxic gas).
Packaged in steel cylinders or glass bottles for solutions; store in cool, ventilated areas away from bases per Sigma-Aldrich specifications.
