Widely used as a UV absorber in polymer systems, this compound protects materials from degradation caused by sunlight and ultraviolet radiation. It is especially effective in plastics, coatings, and adhesives where long-term weatherability is required. Commonly incorporated into polyvinyl chloride (PVC), polycarbonates, and acrylics to prevent yellowing, cracking, and loss of mechanical strength. Also found in outdoor applications such as automotive parts, window profiles, and packaging films. Its ability to absorb UV light in the 300–400 nm range makes it suitable for enhancing the durability of products exposed to solar radiation. Additionally, it is used in some cosmetic formulations to stabilize products against UV-induced breakdown.
