HPLC ELSD Method for Analysis of Distearyl thiodipropionate on Lipak Column

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.
