Colorless to light yellow liqui | [Uses]
(S)-(+)-2-Butanol can be used:
- To synthesize chiral asymmetric perylene diimides (PDI) that spontaneously self-assemble into one-handed nanotubes that are photoconductive or fluorescent in nature.
- To synthesize bulky chiral vinyl monomers that can be radically polymerized to helical polymers with an excess screw sense.
- As chiral solvent to study excited state photo transfer of the photoacid, 5,8-dicyano-2-naphthol (DCN2) in chiral environment.
| [Definition]
ChEBI: (2S)-butan-2-ol is a butan-2-ol. It is an enantiomer of a (2R)-butan-2-ol. |
