Used in fragrance formulations for its floral, slightly sweet, and indolic aroma. It contributes depth and complexity to perfumes, particularly in floral accords such as jasmine, orange blossom, and gardenia. Often employed in small quantities due to its strong odor, it enhances naturalness and richness in fine fragrances, soaps, and cosmetics. Also studied for its potential role as a minor metabolite in biological systems, though its primary use remains in the perfume industry.
