| Molecular Formula | BBr3 |
| Molecular Weight | 250.53 |
| Appearance | Colorless to pale yellow fuming liquid |
| Packaging | 100g/500g/1kg/PTFE-coated glass bottle or stainless steel cylinder; 5kg/25kg/steel drum with PTFE liner (for industrial use); packed under inert atmosphere (nitrogen or argon) |
| Testing Indicators | Appearance — Visual inspection; Identification — FTIR or Raman spectroscopy; Assay — Titration (silver nitrate for bromide after hydrolysis) or ICP-OES (for boron); Purity — GC or ICP-MS (trace metals); Boiling point — Distillation method; Free bromine (Br₂) content — Colorimetry or iodometric titration; Non-volatile residue — Gravimetry after evaporation; Water content — Karl Fischer titration (specialized technique due to reactivity); Chloride content — Ion chromatography. |
| Storage Notes | Stored in a tightly sealed PTFE-lined or glass container under inert atmosphere (nitrogen or argon) in a cool, dry, well-ventilated area; protected from moisture and water (reacts violently); away from heat sources, open flames, incompatible materials (alcohols, water, bases, active metals), and direct sunlight; store separately from combustible materials. |

Used as a strong Lewis acid and brominating agent in organic synthesis; for selective demethylation and dealkylation of ethers (particularly methyl ethers) to phenols and alcohols; as a catalyst in Friedel-Crafts alkylation and acylation reactions; in the synthesis of boronic acids, boronate esters, and boron-containing pharmaceuticals; in the semiconductor industry as a doping agent for silicon; and in the production of high-purity boron.
