| | (S)-(+)-2-Methylbutyric acid Usage And Synthesis |
| Chemical Properties | clear colorless liquid | | Uses | (S)-(+)-2-Methylbutyric acid may be used in the preparation of the stereoisomers of (R)-lavandulyl (S)-2-methylbutanoate and (R)-maconelliyl (S)-2-methylbutanoate, which are female sex pheromones found in pink hibiscus mealybug. | | Uses | (S)-(+)-2-Methylbutyric Acid is a chiral starting reagent used in various synthetic preparations. | | Definition | ChEBI: The (S)-enantiomer of 2-methylbutanoic acid. | | Purification Methods | Purify the acid by distilling it in vacuo [Sax & Bergmann J Am Chem Soc 77 1910 1955, Doering & Aschner J Am Chem Soc 75 393 1953 ]. The methyl ester is formed by addition of diazomethane and has b 112-115o/760mm, [] D +21.1o (c 1.7, MeOH). [Beilstein 2 IV 888.] |
