Descriptors

A pungent, deeply indolic aromachemical with the characteristic naphthalene-like, mothball facet of indoles paired with a warm animalic-floral undertone. In dilution it lends a narcotic, almost fecal-floral depth reminiscent of white flowers (jasmine, orange blossom) with a slightly cleaner, less horsey feel than plain indole. Powerful and long-lasting on the blotter.AI · claude-opus-4-7
