Cyrene has been demonstrated to exceed NMP′s dispersive ability for graphene solutions. Graphene concentrations in Cyrene are an order of magnitude greater than with NMP due to its optimum polarity and high viscosity, creating larger and less defective graphene flakes.
This product is biorenewable and thus aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks".
Cyrene is a biobased dipolar, aprotic alternative to common solvents that are of environmental concern. Cyrene is an alternative for many solvents classified by REACH as Substances of Very High Concern (SVHC), such as N-Methylpyrorrolidone (NMP) and Dimethylformamide (DMF).
In testing, Cyrene has shown to behave similarly to NMP with minimal loss in performance in heteroatom alkylation and nucleophilic fluorination reactions.
