설명

일반 설명

(R)-(-)-a-Methoxy-a-(trifluoromethyl)phenylacetyl chloride (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.

애플리케이션

It was used for derivatizing D-arabinitol and L-arabinitol samples for high performance thin layer chromatography (HPTLC) analysis for studying resolution of the diastereoisomer.
