Used primarily in fragrance formulations for its unique sulfurous, thiol-based character combined with subtle heterocyclic notes. Imparts depth and complexity to perfumes, especially in creating natural-smelling, skin-like or musky accords. Often employed in small concentrations due to high odor potency, contributing to long-lasting scent profiles in fine fragrances, personal care products, and scented consumer goods. Its pyrrole-thiol structure enables strong olfactory impact at low thresholds, making it valuable in enhancing realism in synthetic fragrance blends.
