Hydrogen Bromide Supplier to St. Louis Hydrogen Bromide (Br), a colorless, corrosive, irritating, toxic gas delivered in liquid form via cylinders under its own vapor pressure, is another commercially useful PurityPlus® specialty gas available to St. Louis clients from Cee Kay Supply, Inc.. This gas is produced by the direct reaction of high-purity hydrogen with elemental bromine and the attentively regulated reaction of sulfuric acid on specific brominated metals. Hydrogen Bromide typically has been used for fumigation in agriculture. More discreet measures are used as a catalyst in pharmaceuticals. Earlier on, it was also commonly used in the synthesis of HALON compounds used in fire-suppression systems. This is due to the fact that the resulting HALON compounds are high-density inert gases that can remove ground-level oxygen to extinguish a fire in a enclosed space with minimum damage to property. HBr has come under increasing scrutiny as a stratospheric ozone depleter and, that being the case, its use as a fumigant has been restricted to situations in which total recovery is possible. HALON fire-suppression systems are now dependent on existing chemical inventories as more environmentally preferred alternatives debut. Higher purities of Hydrogen Bromide are used by the electronics industry in a few unique plasma etching processes.
