Used as an intermediate in organic synthesis, particularly in the development of sulfur-containing heterocyclic compounds. It serves as a building block for pharmaceuticals and bioactive molecules due to its structural similarity to chroman derivatives, which are known for antioxidant and neuroprotective properties. Also explored in the design of novel dyes and fluorescent probes owing to its conjugated system and sulfur functionality. Its reactivity allows functionalization at multiple sites, making it valuable in medicinal chemistry research for creating compound libraries.
