Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of anticoagulant drugs such as warfarin and related coumarin derivatives. Its aldehyde and phenolic hydroxyl functional groups allow for selective chemical modifications, enabling the construction of complex aromatic structures. Commonly employed in organic synthesis for introducing the 4-hydroxybenzaldehyde moiety in a protected form, facilitating multi-step reactions where functional group compatibility is crucial. Also utilized in the development of agrochemicals and fine chemicals due to its stability and reactivity profile.
