This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
No disagreement from me. Posting only so the question does not look ignored.
Disagreement-style questions: "I read this and it contradicts what I heard here, which is right?" is answerable. "Is this a bad idea?" without giving the context is not.
Where I would look next, rather than where I would stop.
Confirming post #30 from a second method, which matters more than confirming it from a second person.
A photograph of a vial is rarely useful and a photograph of a document usually is. Redact the identifiers before you post either.
Avoid "any advice?" at the end. It is so generic that people do not know which part of the post it refers to. Pick the specific part and ask that specific question instead.
Post #32 describes the usual case. This is about the unusual one.
If you are asking about a document, quote the exact wording of the line you are asking about. Paraphrasing a specification is how a discussion ends up about a document nobody has read.
Questions you cannot explain: "I cannot say why I am asking this, but is this compound stable at room temperature?" is more productive than no question at all. People here know that some questions cannot be asked in public and they will work with that constraint.
That much is documented. The rest is how I have interpreted it.
Post the arithmetic you already did. Half the questions here are answered by someone spotting which line of your working is wrong, and that is impossible if you only give the answer you got.
The step people skip is the one I have spelled out.
Taking post #38 at face value and following it one step further.

Good question, well framed, and I would like to see it answered properly.

That is all the detail I have. Someone else will have more.
Coming back to post #41, because the follow-up matters more than the original answer.

Post #41 is right about the mechanism and I think understates the practical bit.
Number your questions if there is more than one. It sounds fussy. It means the answer can be numbered back, and you find out which one nobody addressed.
Anyone with a larger sample, please post it.

I had written a reply contradicting post #45 and deleted it. Here is what survived.
Timeline questions need the timeline. Dates, in order, with what happened on each. "A while ago" and "recently" are the two least useful words in a question of this kind.
The right answer here may simply be that it has not been measured.
Right, and stated more narrowly than I would have dared to state it.

One case, stated as one case.
Adding the measurement that post #49 says would settle it.
When you quote a figure from somewhere else, say where from. Not as a formality — the answer frequently depends on whether the number came from a certificate, an independent report or a forum post.
I keep a log of this specifically because memory is unreliable about it.
I will take the caveat as seriously as the claim, which is the point of putting it there.
It is fine to say you cannot explain why you are asking. Nobody will press, and the technical part of the question can usually be answered without the context.

I would rather post the uncertainty than round it away.
I had written a reply contradicting post #50 and deleted it. Here is what survived.
Post the arithmetic you already did. Half the questions here are answered by someone spotting which line of your working is wrong, and that is impossible if you only give the answer you got.
If anyone can point at the primary source I would be grateful.
The arithmetic in post #52 is right; the assumption feeding it is the part to check.
The specific question in the title is more useful than you might think. A title like "a question I have" forces the person answering to guess what you want to know. A title with the actual question gets you an answer in two hours instead of two days.
I have written this out at length because the short version keeps being misread.
Speaking as somebody who asked badly last month and got a polite request for four missing details: writing the question properly the first time takes ten minutes and saves two days. Learn from me.

Not a strong opinion, just a consistent one.
Narrowing post #56, because the general version has more than one answer.

One of those cases where knowing the mechanism does not help the decision.
