General description
2-Isopropylthioxanthone is a compound, which can play the role of a sulfur type photoinitiator in printing industries and UV-cured inks for food packaging materials.
Application
2-Isopropylthioxanthone has been used as an analytical standard for the determination of the analyte in packaged food materials 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, fruit drinks and packaged beverages by high performance liquid chromatography (HPLC) coupled to MS/MS and micellar electrokinetic chromatography techniques (MEKC).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
