Widely used as a UV absorber in polymers and organic materials, this compound protects against degradation caused by ultraviolet radiation. It is especially effective in plastics, coatings, and adhesives where long-term exposure to sunlight can lead to discoloration, embrittlement, and loss of mechanical strength. Its ability to absorb UV light in the 300–400 nm range makes it suitable for applications in automotive parts, exterior building materials, and packaging films. It is also used in combination with other stabilizers, such as hindered amine light stabilizers (HALS), to enhance overall weatherability. Due to its good thermal stability and compatibility with various resins, it is incorporated during processing stages without affecting the clarity or color of the final product.
