A chemical compound found in ambergris, a waxy substance from sperm whales, valued in historical perfumery for its complex aromatic properties.
From 'ambr-' (ambergris/amber) + '-ein' (chemical compound suffix used in chemistry), a technical term from the 19th-century perfume industry.
Scientists isolated ambrein in the 1800s and realized its smell actually comes from chemical breakdown and oxidation—fresh ambergris smells disgusting, but after months aging in the ocean it transforms into liquid gold, proving that time is sometimes the crucial ingredient in perfection.
