Quality Control

Our Triisobutylaluminum is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. Production adheres to relevant ISO 9001 standards, and each lot is analyzed to confirm key parameters such as purity, aluminum content, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and pyrophoric nature, this material must be stored and handled exclusively under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area, away from heat, ignition sources, and oxidizing agents. The container must be kept tightly sealed and upright to prevent leakage and pressure buildup.
