Gallium bromide is an inorganic gallium salt with the chemical formula GaBr₃. It typically appears as a white to pale yellow hygroscopic crystalline solid or powder. As a strong Lewis acid, it readily absorbs moisture, emits fumes in air, and reacts violently with water. This product serves as an efficient catalyst and brominating agent in organic synthesis, while also functioning as a crucial precursor for synthesizing other gallium compounds and semiconductor materials.
We offer high-quality gallium bromide powder in multiple purity grades, supported by professional moisture-proof packaging ranging from gram to kilogram quantities. Contact us for technical support.

Semiconductor precursor material
Organic Synthesis Catalyst: Serves as a strong Lewis acid catalyst to promote various organic reactions including Friedel-Crafts alkylation, acylation, and polymerization.
Semiconductor Precursor Material: Serves as a gallium source for metal organic chemical vapor deposition (MOCVD) or atomic layer deposition (ALD) in preparing III-V semiconductor films like gallium arsenide.
Inorganic Synthesis & Material Preparation: Used as a starting material and brominating agent for synthesizing other gallium salts, complexes, or functional materials.
Research and Education: As a representative strong Lewis acid and hygroscopic compound, it is used in research and teaching experiments for advanced inorganic chemistry and organometallic chemistry.
Q1: How should the product be stored and handled?
A1: Strictly isolate from air and moisture. Must be handled and stored under dry inert gas protection (e.g., in a glove box) using highly sealed specialized packaging.
Q2: What are its primary applications?
A2: Primarily used in catalysis and materials synthesis. Serves as a catalyst in organic synthesis and as a precursor for materials like gallium arsenide in the semiconductor industry.
Q3: What safety risks exist during use?
A3: It is highly corrosive and irritating. It reacts violently with water to produce corrosive hydrogen bromide gas, causing severe irritation to skin, eyes, and respiratory tract. Full protective gear is required during handling.
Q4: How should appropriate purity be selected?
A4: Depends on the application. Ultra-high purity is required for highly reactive catalytic research. For certain synthesis or educational purposes, slightly lower purity grades may be used to control costs, provided strict dehydration protocols are followed.
