Used as an intermediate in the synthesis of pharmaceuticals and dyes. Serves as a matrix in matrix-assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of biomolecules such as peptides, proteins, amines, and amino acids. Employed in the development of antioxidants and UV-absorbing materials due to its phenolic structure. Also utilized in research related to metabolic pathways, enzyme inhibition studies, and as a metabolite of aspirin (acetylsalicylic acid).
