Quality Control

Our Dihydro(2-Methylbuta-1,3-Dienyl)Aluminium is manufactured and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for critical synthetic applications. All materials are analyzed to confirm identity, purity, and reactivity profile. Certificates of Analysis (COA) detailing specific assay results (typically by titration or NMR) and impurity levels are provided with each shipment. We adhere to cGMP principles where applicable to support pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. This material is highly volatile and hygroscopic (moisture-sensitive). It must be stored under a dry, inert atmosphere (argon or nitrogen) in a cool, well-ventilated area, away from heat, ignition sources, and incompatible materials such as strong acids, oxidizers, and water. Recommended storage temperature is 2-8°C for extended stability. Containers must be kept sealed and handled under inert conditions to prevent decomposition.
