Description

General description

We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is biorenewable and thus aligns with ″Safer Solvents and Auxiliaries″ and ″Use of Renewable Feedstocks″. Click Dihydrolevoglucosenone (Cyrene) as a bio-based alternative for dipolar aprotic solvents 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 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.
