UN 1048 Hydrogen Bromide (HBr)
Hydrogen Bromide (chemical formula: HBr) is an important inorganic chemical raw material. It is a colorless gas with an irritating odor, which is easily soluble in water to form hydrobromic acid (a strong acid with strong corrosiveness). It is widely used in pharmaceutical synthesis, perfume preparation, semiconductor etching and other fields. However, it has dangerous characteristics such as high toxicity and strong corrosiveness, so strict compliance with safe operation and regulatory management requirements is necessary. The following is a detailed explanation of its core information and key specifications:
Item | Details |
English Name | Hydrogen Bromide (gaseous state); Hydrobromic Acid (aqueous solution) |
CAS Number | 10035-10-6 (gaseous HBr) |
Chemical Formula | HBr |
Molecular Weight | 80.91 g/mol |
UN Number | UN 1048 (Anhydrous Hydrogen Bromide, compressed/liquefied); UN 1243 (Hydrobromic Acid, aqueous solution) |
Hazard Class | Class 2.3 Toxic Gas (anhydrous HBr); Class 8 Corrosive Substance (hydrobromic acid) |
• Product Quality Testing: The purity of industrial grade hydrogen bromide generally requires ≥99%, and the purity of electronic grade needs to be ≥99.999%. It is necessary to test the impurity content (such as moisture, chlorine gas, elemental bromine, etc.); the concentration of hydrobromic acid is generally 40%-48%, and indicators such as acidity and impurity content need to be tested.
• Occupational Health Testing: The concentration of hydrogen bromide in the workplace must be regularly tested to ensure compliance with the occupational exposure limit requirements; operators must undergo regular occupational health examinations (at least once a year), focusing on examining the respiratory system, eyes and other parts.
