Quality Control

Every batch of (Z)-But-1-Enyldiethylaluminium is manufactured and handled under strict inert atmosphere conditions to ensure purity and consistency. Our products undergo rigorous quality testing, including NMR and titration analysis, to ensure compliance with stringent industry standards for research and process chemistry. Certificates of Analysis (COA) detailing batch-specific purity and assay results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. This material is highly volatile and easily oxidized; it must be stored under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C. Keep away from heat, sparks, open flames, and any source of ignition. Store in a cool, dry, well-ventilated area, segregated from incompatible materials such as oxidizing agents, acids, and water.
