Used in organic synthesis as an intermediate for pharmaceuticals and biologically active compounds. Serves as a building block in the development of adrenergic agents due to the presence of the catechol and amine functionalities. Employed in research settings for the preparation of fluorescent probes and sensors for metal ion detection. Also utilized in the study of antioxidant properties and radical scavenging mechanisms owing to the catechol structure. Suitable for use in analytical chemistry for derivatization reactions.
