    1. Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide is a photo initiator, used in many kinds of ink industries

    2. TPO can be used in the photo-crosslinking of PMMA composite, which can further be used as a gate insulator in organic thin film transistors (OTFTs).

    3. It can also be used in the formation of UV curable urethane-acrylate coatings.

    4. It may also be used in the photoinduced reaction for the formation of organophosphine compounds, which potentially find their usage as ligands with metal catalysts and reagents.
