用途NMRにおける光学異性体比の測定。
使用(R)-(+)-alpha-Methoxy-alpha-(trifluoromethyl)phenylacetic acid is widely used reagent for determination of optical purities of alcohols and amines by 1H or 19F NMR.
一般的な説明Mosher′s acid chloride is generally used as a chiral derivatizing agent. It is easily available in enantiomerically pure form. It can form diastereomers with both alcohols and amines.
純化方法A likely impurity is phenylethylamine from the resolution. Dissolve the acid in Et2O/*benzene (3:1), wash with 0.5N H2SO4, then water, dry over magnesium sulfate, filter, evaporate and distil it. [Dale et al. J Org Chem 34 2543 1969, J Am Chem Soc 75 512 1973.]
