white fine crystalline powder or needles | [Uses]
(R)-(-)-α-Methoxyphenylacetic Acid is a useful synthetic intermediate. It is used as a reactant in the synthesis of dopamine receptor agonists. It can also be used to prepare hydroxytriamides as potent γ-secretase inhibitors. | [General Description]
(R)-(?)-α-Methoxyphenylacetic acid is a chiral derivatizating agent, which is employed for derivatizing enantiomers into diastereoisomers. | [Purification Methods]
Purify the acids by recrystallising from *C6H6/pet ether (b 80-100o). [Neilson & Peters J Chem Soc 1519 1962, Weizmann et al.
