sostanza chimica stabile

[violapais]

I would need to translate "Stabile in condizioni normali". I'm talking about a chemical product. I sincerely don't know if "Stable in standard status" could be acceptable.
Help! Thank you.

Stable in standard conditions

Perhaps "stable under standard conditions" or "stable under normal conditions",
but it would depend on the exact sentence.
