Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. It serves as a building block for antioxidants due to the presence of catechol-like structure, which can scavenge free radicals. Also employed in the development of UV-absorbing compounds and in the synthesis of flavonoids and other polyphenolic derivatives with biological activity. Its reactivity allows for easy modification in the production of dyes, fragrances, and functional materials.
