Rabbit Ear Aldehyde…

A while ago there was an article on LinkedIn discussing the removal of butylphenyl methylpropional and hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC) from the Perfumers’ Palette due to regulations, and the use of floral pyranol, as one of the aroma chemicals that can be used instead to create a lily of the valley note.

But there was mentioned in this article, “rabbit ear aldehyde” and as I’m a chemist as well as a perfumer, I’d love to know what molecule this relates to. It is presumably another lily note. Could it be cyclamen aldehyde, because that has a structure such that in it’s molecular diagram, the carbons and the branching are a “Y” shape? Indeed cyclohexanemethanol, 4-(1-methylethyl)-, cis- (CAS no. 5502-75-0) also has this feature as part of its structure. Or are they talking about the floral pyranol itself in this way, as “Rabbit Ear Aldehyde”? I would love to know.

I haven’t been able to find out definitively, it is a translation from another language, anyway, I love the name and the idea. If anyone knows the answer to this, please let me know in the comments.

“Perfect for Easter fragrances!” quipped my work colleague!

Update: since I wrote this, I have found pictures with a CAS number, 103-95-7, so I have a little more certainty it could be cyclamen aldehyde.
