My assumption of your situtation is that you are spelling something wrong. The denaturing of ethanol is AFAIK mostly due to taxation. They do not want to sell you something cheap and tax free, that can be consumed to achieve a good head buzz. Kontes is a glasware manufacturer. Denaturation has to do with the addition of non consumable alcohols to render a consuble alcohol (non consumable), i.e. addition of IPA, meoh, or other alcohols that are not advisably consumed.
As far as the CAS 108-10-1 (Sunlight is correct) that refers to MIBK, (not something you want to ingest) Methyl Isobutyl Ketone.
Denaturation can be achieved by many means of addition of non consumable agents.
Despite what you may think, denatured etoh, is not another name for methanol. Ethanol may be denatured with methanol, but that is not always the case. It may be denatured, with IPA, or in this case MIBK.
As far as it's compatibility with reductive amination, you would have to have some help with some bees that know a little more about organic chemistry than meeeeee......
