HPLC LC MS Method for Analysis of Distearyl thiodipropionate on Lipak Column

June 30, 2026

HPLC Method for Analysis of Distearyl thiodipropionate on Lipak Column by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Distearyl thiodipropionate.

Distearyl thiodipropionate, also written as DSTDP, is a compound with the chemical formula C42H82O4S. It is an organo-sulfur that is primarily used as a secretary antioxidant and heat stabilizer in organic polymers, cosmetics, and industrial materials.

Distearyl thiodipropionate can be retained and analyzed using the Lipak stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a sulfuric acid buffer. Detection is performed using LC MS.

Separation of Distearyl thiodipropionate on Newcrom R1 HPLC column

February 16, 2018
Separation of Distearyl thiodipropionate on Newcrom C18 HPLC column

Distearyl thiodipropionate 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.
