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

General description
2-Methyltetrahydrofuran (2-MTHF), a 2-methyl substituted tetrahydrofuran, is a biomass derived solvent. It is a potential greener solvent alternative for organic synthesis. It shows resistance to reduction by lithium making it a promising candidate as electrolytes in lithium batteries.[1] Its polarity and Lewis base strength is intermediate between tetrahydrofuran (THF) and diethyl ether. The ring opening reaction of 2-MTHF has been studied using acid chloride and iodide.
Application
It may be used as an alternative solvent to:
- Dimethyl sulfoxide (DMSO) or methyl tert-butyl ether (MTBE) in the C-C bond forming reactions catalyzed by lyase enzyme.
- Tetrahydrofuran (THF) in the reaction between Grignard reagents and carbonyl compounds.
- Methylene chloride in some biphasic reactions.
