Description

Triethylborane is a highly reactive organoboron compound primarily used as a versatile catalyst and reagent in organic synthesis. Its value lies in its ability to initiate and control polymerization reactions and facilitate key chemical transformations with high efficiency. This product is essential for R&D laboratories and industrial-scale production in the pharmaceutical, agrochemical, and advanced materials sectors, where precise chemical synthesis is critical.

Application

• Polymerization Catalyst: A key initiator for olefin polymerization, particularly in the production of polyolefins and specialty polymers.
• Organic Synthesis Reagent: Used in hydroboration reactions, radical chemistry, and as a source of ethyl groups in cross-coupling reactions.
• Fuel Additive: Acts as an ignition promoter and combustion catalyst in high-performance rocket and jet fuels.
• Semiconductor Manufacturing: Employed in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes for thin-film growth.
• Pharmaceutical Intermediate: Facilitates the synthesis of complex organic molecules and active pharmaceutical ingredients (APIs).
• Reducing Agent: Used in specific reduction reactions within fine chemical manufacturing.

Quality Control

Our Triethylborane is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and solvent residue analysis. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (nitrogen or argon) in a cool, dry, well-ventilated area, away from heat, ignition sources, and incompatible materials. Due to its highly volatile and pyrophoric nature, it must be handled exclusively under inert conditions. Recommended storage temperature is 2-8°C for extended stability.
