High-purity boron trifluoride (BF₃) gas supplied from China for organic synthesis, catalysis, and industrial processing.
High-purity boron trifluoride (BF₃) gas for esterification, alkylation, polymerization, and semiconductor manufacturing.
Boron trifluoride is a colorless gas with a sharp, pungent odor at room temperature. As a strong Lewis acid, it is soluble in cold water, concentrated sulfuric acid, and most organic solvents. It is non-combustible and does not support combustion, but reacts vigorously with moist air to produce dense white fumes. At room temperature, it corrodes glass, and wet boron trifluoride is highly corrosive. Boron trifluoride serves as an efficient catalyst in various organic reactions, including esterification, alkylation, polymerization, isomerization, sulfonation, and nitration. It is also used in semiconductor manufacturing, petroleum refining, and as a key raw material for producing boron compounds, typically transported as a liquefied compressed gas.
Global Shipping & Export Compliance
Boron trifluoride (UN 1008) is classified as a toxic and corrosive compressed gas and must be handled under strict hazardous materials regulations.
- Sea freight (FCL / LCL) – standard export method
- Air freight – limited availability (regulatory controlled)
Required Export Documents
- Material Safety Data Sheet (MSDS)
- Certificate of Analysis (COA)
