Application
2,4,6-Trimethylbenzophenone (TMBP, Mesityl phenyl ketone) is a highly effective Type II (hydrogen‑abstracting) photoinitiator widely used in UV‑curable coatings, inks, adhesives, and photopolymerization systems. It is often formulated as a liquid eutectic mixture with 4‑methylbenzophenone (e.g., Esacure TZT) to deliver high reactivity, excellent solubility, low curing odor, and minimal yellowing. TMBP is particularly indicated for photopolymerization of UV systems where high cure speed and low discoloration are critical. It also serves as a versatile organic intermediate for synthesizing pharmaceuticals (including anxiolytics and hypnotics), agrochemicals, dyes, and specialty chemicals. In sunscreen research, TMBP is used as a model compound for predicting estrogenic activity of UV filter ingredients.
