A Reproducible Method for Analysis of an Oxonium Salt
A rapid, sensitive, and Reproducible Method has been developed for Analysis of p-Toluenesulfonic Acid Monohydrate. The data below, (an overlay of 5 chromatograms ) illustrates how the compound can be adequately Retained and detected using this straightforward Method.
Column: Cogent Phenyl Hydride™, 4μm, 100Å
Dimensions: 4.6mm x 75mm
Mobile Phase: (85:15) DI Water / Acetonitrile with 0.1% Formic Acid
Injection vol.: 2μL
Flow rate: 1.0mL / minute
Detection: UV @ 210nm
Sample Preparation: p-Toluenesulfonic Acid Monohydrate prepared as 1.0mg / mL Standard Solution in DI Water
Notes: p-Toluenesulfonic Acid Monohydrate is widely used as catalyst agent in the synthesis of pharmaceuticals, pesticides, polymerization stabilizer and organic synthesis (esters, etc.), paint intermediates and resin curing agent.
