Aluminum bromide
Aluminium bromide (CAS 7727-15-3, formula AlBr3, molar mass 266.69 g/mol) is an anhydrous inorganic aluminium salt supplied as a solid of 99.999% (trace metals basis) purity. It is a strong, highly moisture-sensitive Lewis acid that reacts violently with water and fumes in moist air. Widely used as a catalyst in organic synthesis, including Friedel–Crafts alkylation and acylation, it serves chemical research and fine-chemical manufacturing. Tech Serve Solutions supplies and exports it worldwide.

Lewis acid catalyst
Aluminium bromide is a powerful Lewis acid used to catalyse a range of organic transformations. It activates substrates by accepting electron pairs, making it valuable in synthetic and process chemistry.
Friedel–Crafts reactions
It is a well-established catalyst for Friedel–Crafts alkylation and acylation of aromatic compounds, promoting carbon–carbon bond formation in the preparation of substituted aromatics and intermediates.
High-purity inorganic synthesis
Supplied at 99.999% on a trace-metals basis, this anhydrous grade suits applications where low metallic impurity is important, including catalysis and inorganic chemistry research.
Research and laboratory reagent
Aluminium bromide is used as a reference inorganic salt and reagent in academic and industrial laboratories studying aluminium chemistry, Lewis-acid catalysis and bromination.
Materials and inorganic chemistry
As a source of aluminium and bromide, it is employed in materials science and inorganic preparations. It is also available as a 1.0 M solution in dibromomethane for controlled handling.

What is Aluminium bromide used for?
+
Aluminium bromide (AlBr3) is mainly used as a strong Lewis acid catalyst in organic synthesis, notably Friedel–Crafts alkylation and acylation of aromatic compounds. It also serves as a high-purity inorganic reagent in catalysis, materials science and laboratory research.
What is the CAS number and molecular formula of Aluminium bromide?
+
Aluminium bromide has the CAS number 7727-15-3 and the empirical formula AlBr3 (Hill notation). Its molecular weight is 266.69 g/mol, the EC number is 231-779-7 and the MDL number is MFCD00003421.
What grade and purity does Tech Serve Solutions supply?
+
We supply Aluminium bromide as an anhydrous solid with an assay of 99.999% on a trace-metals basis, and can offer a 1.0 M solution in dibromomethane. It is provided as a high-purity research and reagent grade; we do not represent it as USP, BP or EP pharmacopoeial grade. Detailed specifications are available on request.
What are the safety and handling hazards of Aluminium bromide?
+
Aluminium bromide is classified Danger (GHS05, GHS07) with hazard statements H302 (harmful if swallowed) and H314 (causes severe skin burns and eye damage). It reacts violently with water. Handle under dry, inert conditions away from moisture, using eye and face protection, gloves and a suitable respirator; consult the SDS before use.
How is Aluminium bromide packed, shipped and exported?
+
Because it is moisture-sensitive and corrosive, Aluminium bromide is packed in sealed, moisture-protected containers and recommended storage is 2–8°C. It is classified for transport as UN 1725, Class 8 (corrosive), Packing Group II, and is shipped as dangerous goods under applicable regulations. We export worldwide with appropriate documentation.
