A compound known for being an ingredient in the overwhelming majority of all perfumes made. The popularity and widespread usage is down to the versatility and malleability of the compound — imparting its value easily, readily, and in any fragrance that requires it. It is found in crystal form; naturally occurring on a multitude of plants like the tonka bean. The aroma is spicy, sweet, herbaceous, and fresh; akin to a blend of almonds and vanilla, with hints of aged plant materials. It is often added to compositions to give a sense of creeping sweetness that rises as the scent wafts. The scent also lasts much longer than other scents; a characteristic that it can inject into the compositions it is added to. This makes the compound extremely valuable in the world of perfumery, and is the reason for its widespread appeal.

It also makes the foundation for the fragrance family of fougère. In perfumery, it is rarely an organic material of which the cumarin compound has been derived for usage.

Musc Ravageur from the Edition de Parfums Frédéric Malle contains Cumarin for example.
