How it smells
The seed that redefined modern fragrance
Coumarin, the compound that makes tonka irresistible, was the first synthetic aroma molecule used in perfume, debuting in 1889.
Origin
Venezuela
Long before tonka bean earned its place in fine fragrance, it served a simpler purpose: perfuming cupboards. Crushed and powdered, these Amazonian seeds were sold in small sachets throughout Central and South America, bringing their sweet warmth to stored linens and clothing. The discovery of coumarin in 1820 changed everything.
When English chemist William Henry Perkin synthesized coumarin in 1868, he opened a door that would reshape perfume history. The molecule appeared in Guerlain's Jicky that same year, becoming the first synthetic fragrance compound to enter a prestige perfume. Today, while natural tonka absolute remains precious and regulated due to coumarin restrictions in the United States, its influence persists.
Over 30 percent of commercial fragrances contain coumarin in some form, a testament to the modest seed from the Amazonian rainforest that transformed an industry.

The essentials on Mung Bean in perfumery: how it smells, where it comes from, and how it behaves on skin.

When was coumarin first synthesized?
English chemist William Henry Perkin synthesized coumarin in 1868. His discovery enabled affordable production of the molecule, democratizing the warm, sweet note across the fragrance industry.
