(S)-(-)-alpha-Methoxy-alpha-(trifluoromethyl)phenylacetic acid, 99%
CAS: 17257-71-5 | C10H8F3O3 | 233.17 g/mol
Supplier: Thermo Scientific Chemicals B23117ME
Description
(S)-(-)-alpha-Methoxy-alpha-(trifluoromethyl)phenylacetic acid is used as a chiral derivatizing agent, it reacts with an alcohol or amine of unknown stereochemistry to form an ester or amide. The absolute configuration of the ester or amide is then determined by proton and/or 19F NMR spectroscopy.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
