I can't honestly think of a finished fragrance with a prominent note of either C8 or C9. The acme of aldehydic fragrances - Chanel Number 5 - uses C10, C11 and MNA in heavy doses.
To be honest I don't find a lot of use for the lower numbered aldehydes except as a citrus booster, and even then, as David says, C10 gives a clearer citrus note.
Thanks for the kind remarks on my work by the way - is that Green Carnation and Anjin you're referring to?
