solutions are more stable than neat product


Prices denominated in other currencies on request (USD, PLN, GBP, CHF, AUD, CAD)

We offer also the product in the form of stabilized solution, where carbon diselenide composes an adduct with special solvents. Such solutions are more stable and may be used in this form or carbon diselenide can be recovered after evaporation of solvent.
