Description

General description

A mixture of 4-isopropylthioxanthone and 2-isopropylthioxanthone can be used as photoinitiator in ultraviolet(UV)inks, which finds applications in plastic or paper based packaging materials.

Application

4-Isopropylthioxanthone has been used as an analytical standard for the determination of the analyte in packaged food products using liquid chromatography-tandem mass spectrometry (LC–MS/MS). It may be used as an analytical standard for the determination of the analyte in milk, and fruit drinks by high performance liquid chromatography (HPLC) coupled to MS/MS and micellar electrokinetic chromatography (MEKC) techniques, respectively.
