HPLC Determination of Stearyl Methacrylate on Newcrom R1 Column
April 30, 2020
View on hplc.cloud
Stearyl methacrylate is used for manufacturing polymers as well as an oil additive for viscosity adjustments. Stearyl methacrylate can be retained in HPLC on Newcrom R1 column using anhydrous conditions with the mobile phase consisting of methanol (MeOH) and acetonitrile (ACN) with no buffer necessary. The analysis method is MS-compatible and can also be UV detected at 230nm

| Mobile Phase | MeCN/MeOH – 80/20% |
| Buffer | No |
| Flow Rate | 1.0 ml/min |
| Detection | UV 230 nm, MS-compatible mobile phase |
| Class of Compounds | Hydrophobic, Neutral |
| Analyzing Compounds | Stearyl Methacrylate |
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.

Separation of Stearyl methacrylate on Newcrom R1 HPLC column
February 16, 2018
Stearyl methacrylate 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.
