Description générale

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.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

A fast screening method is presented for detecting isopropylthioxanthone (ITX) contamination in milk. The method is based on direct high-performance liquid chromatography/tandem mass spectrometry (HPLC/MS/MS) analysis of milk samples. Sample preparation is limited to the addition of a deuterated ITX
