Aplicación

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Tetrahydrofuran may be used as an extraction solvent for the determination of pesticide residues in olive oil[3] and phthalates in toys and child care articles[4] by chromatography techniques.

Tetrahydrofuran may find application as a solvent in the synthesis of (S)-2-(1-pyrrolidinylmethyl)pyrrolidine.[5] It is also an excellent solvent for sodium diisopropylamide, which can find applications as an effective base for the isomerization of alkenes and metalation of 1,4-dienes.[2][6]
