Description générale

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

Caractéristiques et avantages

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

Questions

1–5 of 5 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  3. What is a BioRenewable solvent?

    1 answer

    1. 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.

      Helpful?

  4. Why should you use BioRenewable solvents?

    1 answer

    1. 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.

      Helpful?

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

    1 answer

    1. 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.
