Civetone

Civetone is a macrocyclic ketone and the main odorous constituent of civet oil.[1] It is a pheromone sourced from the African civet. It has a strong musky odor that becomes pleasant at extreme dilutions.[2] Civetone is closely related to muscone, the principal odoriferous compound found in musk; the structure of both compounds was elucidated by Leopold Ružička.[3] Today, civetone can be synthesized from precursor chemicals found in palm oil.[4]

Uses

Civetone is used as a perfume fixative and flavor.

In order to attract jaguars to camera traps, field biologists have used the cologne Calvin Klein's Obsession For Men. It is believed that the civetone in the cologne resembles a territorial marking.[5]

gollark: So it's cheaper to build on an oxygenated planet where you can make arbitrarily big facilities cheaply.
gollark: Even if it does have all the basic stuff, you need *more* of that as they get bigger.
gollark: The problem is though, space stations are very expensive to expand because oxygen and airlocks and stuff.
gollark: Realistically, people *will* end up making permanent settlements because it's convenient and ships have limited volume.
