The storage lookup and where its data comes from — setting out what I have, and where I think it stops being reliable.

Working notes on storage lookup rather than a conclusion. I would rather post the reasoning while it can still be corrected than post the answer once I am committed to it.

Everything below is checkable. Where I have taken a figure from somewhere else I have said where; where I have estimated, I have said that too.

Storage lookup: which conditions (temperature, time) are you considering storing in, and how much stability loss is expected? The calculator gives a rough estimate based on typical stability data. Not a substitute for your compound's specific stability data.

I would rather post the uncertainty than round it away.

r.coelho, post #3: Since storage lookup keeps coming up, it should probably be a maintained page rather than a recurring thread. I am happy to draft it if someone with more direct experience will review it. Go to post

Rounding behaviour is where two tools disagree. One rounding to the nearest graduation and one to two decimal places will produce different advice from identical inputs.

Post #3 put the caveat in the right place and I want to underline it.

I would call the community position on storage lookup likely rather than established, and I would be comfortable defending that hedge.

Thank you — that answers what I came here to find out.
