Separation of Acetic acid, (triphenylphosphoranylidene)-, methyl ester on Newcrom R1 HPLC column

February 19, 2018
Separation of Acetic acid, (triphenylphosphoranylidene)-, methyl ester on Newcrom C18 HPLC column

Acetic acid, (triphenylphosphoranylidene)-, methyl ester can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.

Application Column

Newcrom R1

The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
