How It Works
Ethylaluminum sesquichloride is an organometallic compound that functions as an alkylating / co-catalyst component in coordination polymerization systems (for example Ziegler-Natta and metallocene processes) and as a reducing or initiating reagent in fine-chemical synthesis. Many metal alkyls are pyrophoric and react violently with water, so they are supplied and handled under inert atmosphere.
Primary Applications
EASC is applied across Ziegler-Natta Catalysis, Polymerization. Typical market segments include Polymer Production.
Its performance profile makes it a trusted choice for formulators who need reproducible,
high-purity raw materials.
Safety, Handling & Storage
Handle EASC in accordance with its Safety Data Sheet (SDS). Store in original,
sealed packaging away from heat, ignition sources and incompatible materials, within the
recommended temperature range. Personal protective equipment and adequate ventilation are
required. Always consult the current SDS and applicable local regulations before use.
