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 "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. What is a BioRenewable solvent?

    BioRenewable solvents are sourced from renewable and sustainable biobased materials, such as soy/palm oil, wood waste, hay or corn byproducts, etc. It is important to highlight that our BioRenewable products do not compete with food production.

  2. Why should you use BioRenewable solvents?

    You will contribute to create a sustainable world, significantly lowering environmental impact. Biorenewable solvents also decrease petroleum sources dependency, have higher recovery rates, and/or are safer for handling and disposal.

  3. Do BioRenewable solvents have a similar quality to petroleum-based solvents?

    BioRenewable solvents can have the same or higher purity level compared to traditional solvents. These solvents are free of the many byproducts of petroleum manufacturing, such as benzene, aldehydes, and ethers.

Pd-catalysed C-C bond formation is an essential tool within the pharmaceutical and agrochemical industries. Many of these reactions rely heavily on polar aprotic solvents; however, despite their utility, these solvents are incompatible with the drive towards more sustainable chemical synthesis.
