Each odorant molecule must be small enough to be volatile. No one has described an odor-producing molecule with a molecular weight greater than 294. This appears to be the size limit for a molecule to have sufficient volatility to be detected by the nasal receptors.
I don’t believe this MW of 294 limit to be correct.
If you reference this page:
http://www.thegoodscentscompany.com/data/rw1005761.html
you can note the MW of 325.364 for this molecule.
A molecule that drove the famous perfume of the 1980’s, Giorgio.
Your information seems to be incorrect, or woefully out of date.
This week, I have been making molecules with MW over 400. And I can smell them.
Fragrantly yours,
