General description
4-Methylbenzophenone is a photo-initiator for printing inks, mainly applied to the cardboard boxes used for packing. It is reported to be a non-genotoxic carcinogen. However, it can contaminate foodstuffs when it comes in contact with the package contents.
Application
4-Methylbenzophenone may be used as a reference standard for the determination of the analyte in breakfast cereals, paperboard food packaging and packed milk by various chromatography techniques.
Analysis Note
The purity is calculated based on the principle of mass balance and is mentioned on the CoA
