Not sure if it is a panteted molecule (IFF).
It is piercing, woody, resinous, musty and rosy in some ways. It is peculiar and interesting, not sure to have smelled anything that resembles this until now. Not at all ozonic (like Floralozone or Precyclemone B) nor marine, as stated in some descriptions; it has no lily of the valley-melon-like nuance. A little bit salty, maybe.
It is the odour you could find in a cellar, quite thin and volatile. This has not much body but is quite long-lasting. I very much appreciate its extremely dry, woody, musty, cork-like undertones.
It is quite powerful, difficult to use at more than 5%.
