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 it aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks".  Click here  for more information.

2-Methyltetrahydrofuran (2-MTHF), a 2-methyl substituted tetrahydrofuran, is a biomass derived, environmentally favorable solvent alternative to tetrahydrofuran (THF), 1,4 Dioxane (Dioxane) and dichloromethane (DCM) for most industrial applications. Its polarity and Lewis base strength is intermediate between tetrahydrofuran (THF) and diethyl ether. It is a potential greener solvent alternative for organic synthesis and shows resistance to reduction by lithium making it a promising candidate as electrolytes in lithium batteries.

Application

2-Methyltetrahydrofuran may be used as an alternative solvent to:
THF in organometallic reactions
  • Grignard
  • Reformantsky
  • Lithiation
  • Hydride Reduction
  • Metal-Catalyzed Coupling (Heck, Stile, Suzuki)




Dichloromethane for Biphasic Reactions:
  • Alkylation
  • Amidation
  • Nucleophilic Substitution

Features and Benefits

  • Made from Renewable Resource - furfural derived from agricultural byproducts
  • High boiling point
  • Clean organic-water phase separation
  • Reduced energy to recover

  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.
