How I would do it:
You're not allowed to take liquids with you as hand baggage. You'll need to store it in the suitcase you check in before you go through the security zone.
I don't think sniffer dogs can detect N, so that won't be a problem.
I would probably buy a bottle of water and pour the N into it disguising it as being simply water.
It would surprise me if the scans and checks they may be running picks up on it.
Theres some risk to this, sure, but that's unavoidable.
The trick is to not draw attention to yourself, and disguise this precious liquid as something ordinary they see every day.
Being overly zealous in disguising it could potentially draw attention.
If you get caught I don't think they'll put you in jail. If that happens you should simply be honest and say it's for your personal use and you intent to CTB with it.
As long as you're not believed to be trafficking or selling the stuff you'll probably just get a fine.
You should check out the PPH and see what happens in different countries when you get caught with a small amount of N.
Maybe even read up on the law yourself to prepare for the consequences.
