Stability/Storage of nitropropenes

[horffao1]

New to phenethylamine/amphetamine chemistry and looking at a few Shulgin recipes. How stable are the nitropropenes and what's the best way to store them? Based on timing, availability of chemicals, etc. I am thinking of processing all my benzaldehyde, taking down the lab, several weeks or months later resume with the nitropropene -> amphetamine.

Keep them clean (recrystallization or vacuum distillation) In the fridge thy will last forever.

Perfectly dry in vacuum packaging or just dense packaging without access to moisture and air in a cool dark place. In ideal conditions, storage period without problems is about 1 year.
