Frequently asked questions
What is branched polyethyleneimine (M.W. 600) commonly used for?
Branched polyethyleneimine (M.W. 600) is widely used as a **flocculant**, **gene delivery reagent**, **corrosion inhibitor**, and **epoxy curing agent** due to its high density of amine groups for cross-linking and adhesion.
What is the chemical formula and molecular weight of this product?
The exact formula is a repeating unit of **(-CH₂-CH₂-NH-)x** with side chains, but the precise structure varies by branching. The nominal molecular weight is **~600 g/mol** (average).
How should Polyethyleneimine (branched, M.W. 600) be stored?
Store in a **tightly sealed container** at **ambient temperature (20–25°C)**, away from strong oxidizers, acids, and moisture to prevent gel formation or degradation.
What grades or purity levels are available for this product?
Molekula supplies this product in **technical grade (typically ≥99% purity)** and can provide **analytical certificates** upon request to confirm amine content and impurities.
Can Molekula supply branched polyethyleneimine (M.W. 600) in bulk quantities?
Yes, we offer **bulk packaging options** (drums, IBCs) for quantities starting at **5 kg**, with flexible MOQs depending on application and customer requirements.
What documentation is provided with an order of this product?
