This product is BioRenewable and thus aligns with "Designing Safer Chemicals", ″Safer Solvents and Auxiliaries″ and ″Use of Renewable Feedstocks″. Click here for more information.
Cyrene is a biobased dipolar, safe for end-of-life disposal, decomposing into CO2 and H2O. It is an 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-Methylpyrrolidone (NMP) and N,N-Dimethylformamide (DMF).

Application
Cyrene has been applied in replacement of NMP and/or DMF in some applications, such as demonstrating to exceed NMP′s dispersive ability for graphene solutions due to its optimum polarity and high viscosity, creating larger and less defective graphene flakes. Find below more uses for Cyrene™.
1. Dispersive ability for graphene solutions.
2. Alternative to DMF in the synthesis of metal-organic frameworks.
3. Organic synthesis:
1. Dispersive ability for graphene solutions.
