Used primarily as a photoinitiator in UV-curable systems, this compound plays a key role in polymerization processes triggered by ultraviolet light. It is commonly found in inks, coatings, and adhesives where rapid curing under UV light is required. Its ability to generate free radicals upon exposure to UV radiation makes it effective in promoting fast drying and hardening of thin films. It is often paired with other photoinitiators to enhance curing efficiency and reduce yellowing in the final product. Due to its moderate volatility and good solubility in organic matrices, it is suitable for formulations requiring consistent performance and shelf stability.
