Applicazioni

(R)-(-)-α-Methoxy-α-(trifluoromethyl)phenylacetyl chloride is used as a chiral acylating reagent, which is used in the resolution of amino acid enantiomers like 2,5-dimethoxy-4-methylamphetamine. It is also suitable for the determination of the optical composition of compounds extracted from biological fluids.

Note

Moisture sensitive. Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place.
