4-Chloromandelic acid Usage And Synthesis
Chemical Propertieswhite crystalline powder
Uses4-?Chloromandelic acid has been used as a catalyst for Michael Addition of 2-?(1-?Ethylpropoxy)?acetaldehyde to N-?[(1Z)?-?2-?Nitroethenyl]?acetamide. As well, it has been used as a nucleation inhibitor for dutch resolution for diastereomers of racemic 3-?methoxyphenylethylamine with chiral mandelic acid.
