Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. It plays a key role in the synthesis of vanillyl derivatives, which are important in the development of bioactive compounds, including potential analgesics and anti-inflammatory agents. Its reactivity allows for the introduction of bromine-containing functional groups into more complex molecules, making it valuable in medicinal chemistry research. Also utilized in the production of flavor and fragrance compounds due to its structural relation to vanillin.
