Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides due to its stable aromatic structure and reactive chlorine sites. Its benzofuran core is valuable in creating bioactive molecules, and the compound serves as a building block in organic reactions where selective substitution is required. It also finds use in research for designing new functional materials and in the preparation of fluorescent dyes and optical brighteners because of its conjugated system.
