Used as an intermediate in organic synthesis, particularly in the preparation of photochromic compounds and UV-absorbing agents. It plays a role in the development of light-sensitive materials due to its ability to undergo reversible structural changes under UV radiation. Commonly applied in the formulation of photochromic lenses, coatings, and specialty polymers where controlled response to sunlight is required. Also investigated for use in sensors and optoelectronic devices due to its distinct photochemical behavior.
