| Chemical Properties | Aluminum Bromide exists primarily in the anhydrous and hydrated forms. The anhydrous form is a molecular compound with high reactivity, easily decomposing upon heating. It reacts vigorously with water and other Lewis bases. Hydrated forms exhibit ionic characteristics and can exist as dimers or polymers. |
| Applications | Used as a catalyst in organic synthesis, particularly in Friedel-Crafts reactions. It is also used in the preparation of other aluminum compounds and as a reagent in laboratory settings. |
| Safety Precautions | Aluminum Bromide is highly reactive and corrosive. It should be handled with caution and stored in a cool, dry place away from water, oxidants, and incompatible materials. Operators must wear appropriate protective equipment and strictly comply with safety regulations. In case of skin, eye contact, ingestion, or inhalation, seek medical attention immediately. |
