Application

Diethylaluminum chloride solution can be used:
  • As a Lewis acid for the synthesis of Lewis acid-base bifunctional asymmetric catalysts for cyanosilylation of aldehydes and in Strecker reaction.
  • For the synthesis of precursors for lanthanide/aluminum catalysts for diene polymerization.
  • As a co-initiator in the cationic polymerization of isobutylene.

Packaging

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
