Description

Diisobutylaluminium Hydride (CAS NO 1191-15-7) is a highly reactive organoaluminum compound widely used as a powerful and selective reducing agent in organic synthesis. Its primary value lies in its ability to efficiently reduce a variety of functional groups, including esters, ketones, and acid chlorides to their corresponding alcohols, making it indispensable for fine chemical and pharmaceutical manufacturing. This chemical is a critical raw material for researchers and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise and controlled reduction reactions.

Application

• Selective Reduction in Organic Synthesis: A key reagent for the chemoselective reduction of esters, ketones, and acid chlorides to alcohols under mild conditions.
• Pharmaceutical Intermediate Production: Used in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs) where precise stereochemistry is required.
• Polymerization Catalyst & Cocatalyst: Serves as an activator and chain-transfer agent in Ziegler-Natta type olefin polymerization and other catalytic processes.
• Agrochemical Manufacturing: Employed in the synthesis of advanced pesticides, herbicides, and plant growth regulators.
• Fine Chemical Production: Essential for creating specialty chemicals, flavors, fragrances, and other high-value organic compounds.
• Hydroalumination Reactions: Used to add aluminum-hydrogen bonds across carbon-carbon double or triple bonds, creating organoaluminum intermediates for further functionalization.

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 (argon or nitrogen). Store in a cool, dry, well-ventilated area away from heat, ignition sources, and incompatible materials such as water, alcohols, and oxidizing agents. Recommended long-term storage temperature is between 2°C and 8°C to maintain stability.
