facing problem to separate acid and its acid anhydride on HPLc
Hi Yogesh,
it depends on your sample matrix and how complex is it. the first thing i would try is anion exchange - the acid should bind but not the anhydride.
Cheers,
David.
Dear Yogesh:
In what solvent have your analytes?
Thanks.
Best Regards,
Áurea Andrade-Eiroa
Please Explain more? Is it aromatic or aliphatic acids?
4-Dimethyl amino pyridine is used in reaction.Product formed contains amino group along with amide & is highly water soluble. To remove 4-DMAP aqueous work up done. Please give solution. Thanks.
