best way to store anhydrous IPA?

simple, easy question, just wanted to check with the experts.

i'm assuming the best way for long-term storage of anhydrous IPA is to store it in a bottle over 3a molecular sieves. with the bottle air-tight and filled to the top so there's little breathing room in the bottle right?

just want to make sure IPA won't react with molecular sieves over time

The stuff is quite stable. Even with oxygen present in the bottle there should be no oxidation at ordinary temperatures. I am not certain about absorption in molecular sieves, but there should not be any reaction with them unless they contain bonded to them strongly acid groups like -SO3H.
