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:

• Cacchi-type annulation
• Synthesis of urea
• HATU Amide Coupling - Replacement for DMF in amide and dipeptide coupling reactions.
• Suzuki-Miyaura coupling reaction.
• Sonogashira coupling reaction.
• Reductive homocoupling reaction.

Features and Benefits

• 99% biodegradation in 28 days
• Stable during incineration
• Not mutagenic or genotoxic
• ASTM D6866 - Standard Test Methods for Determining the Biobased Content
• Made from Renewable Resource − Cellulose
