Description

Lithium Tris[(3-Ethyl-3-Pentyl)Oxy]Aluminohydride is a specialized, non-pyrophoric reducing agent belonging to the family of alkoxyaluminum hydrides. This compound matters for its ability to provide controlled, highly selective reduction of various functional groups, including ketones, aldehydes, and acid chlorides, under mild conditions. It is primarily needed by R&D chemists and process development teams in the pharmaceutical, agrochemical, and fine chemical industries for complex synthesis where precise stereochemistry and functional group tolerance are critical.

Application

• Selective Carbonyl Reduction: For the controlled reduction of ketones and aldehydes to secondary and primary alcohols, respectively, with high chemoselectivity.
• Pharmaceutical Intermediate Synthesis: A key reagent in multi-step syntheses of active pharmaceutical ingredients (APIs), particularly for chiral alcohol building blocks.
• Fine Chemical Manufacturing: Used in the production of specialty chemicals, flavors, fragrances, and advanced materials requiring precise reduction steps.
• Asymmetric Synthesis: Employed in conjunction with chiral ligands or auxiliaries for enantioselective reduction reactions.
• Polymer Chemistry: Acts as a reducing agent or catalyst component in the synthesis and modification of specialty polymers.
• Hydrogen Storage & Energy Research: Investigated in advanced material science for its potential in hydrogen storage applications due to its hydride content.

Quality Control

Our Lithium Tris[(3-Ethyl-3-Pentyl)Oxy]Aluminohydride is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity for demanding synthetic applications. Each lot is analyzed to confirm identity, purity, and reactivity profile. Certificates of Analysis (COA) detailing specific test results are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool (15-25°C), dry, and well-ventilated area, away from moisture, heat, and incompatible materials. Due to its hygroscopic and highly volatile nature, containers must be kept sealed and handled under inert conditions to maintain product integrity and safety.
