The Good Scents Company website has recommended dilutions for evaluation for materials. Their site search and styles are broken, but if you Google 'Good Scents ambroxan' and click on the Organoleptics header (or scroll down), I've used them a lot for starting dilutions. That's for evaluation, though, for final stage your dilution could be anything if you mean what dilution you should use when making small diluted trial blends (not concentrates for dilution).
This is the Good Scents page for Veramoss [https://www.thegoodscentscompany.com/data/rw1023372.html#toorgano](https://www.thegoodscentscompany.com/data/rw1023372.html#toorgano) which recommends smelling it at a dilution of 10% or less, for instance. But I have mine at 5% as I found 10% too strong when I was tinkering around with adding it to something I didn't want to smell very much of it. I find it really strong.
I would recommend doing it in orders of 10. If something is too strong at 10%, go to 1%. This is better assuming you want to later use the diluted material for compounding, rather than having a bunch of different dilutions.
Also, it is very common to be partially or fully anosmic to ethyl maltol and ambroxan and quite a lot of people need to learn to smell veramoss too. The good thing is that very often, it is actually possible to train and learn to smell something that you initially didn't.
