Any bottle? That must cause chaos at Merck or similar. Or can you get away with "well, I stuck foo-bah acyl chloride and yakety amine in there" without saying you ought to have the amide by now.
Exactly. First off, commercial sources always have the CAS# on the label, in addition to multiple names, IUPAC, and common name, in various languages. Your second point is more provocative, in a related task, I've been tasked with labeling my titration waste. Logically, it should be labeled with the products, but legally, they want what goes in, listed.
What about all the intermediates that aren't commercial? Do they have T1 or similar straight to Columbus, OH for instant access CAS-RN allocation?
You can label something with CAS# - unavailable. The New Jersey statute is all about their way of implementing the end-user's "right-to-know." To keep the company from hiding the identity of what their chemists, line workers, and janitors are working with.
It was so weird back where I was working. We had to label each tube, and they were just beginning the implementation as I was leaving. Our products were synthetic biomolecules (oligonucleotides.) It was going to be a system of stick on colored dots, cross referenced to a page taped to the refrigerator -- which was stupid enough (those gummed dots were going to fall off with condensation).
The top component was water, then buffer component acid, and base, then the titrating base to adjust pH -- sodium hydroxide, then, oligo -- which had an unknown CAS#. And that's it -- different oligos, but the same CAS label. But -- ah -- we were in production -- before it was finalized, it might be in plain water, or just buffer, or in NaOH solution, or ... with a tag for each.
For another product, there was another mixture, with water, a different buffer, KOH (yep, you list it like you make it, and ignore the KOH is really gone, and the buffer has been titrated to a mix of acid and base), and a supporting salt, and EDTA -- opps, that's 5 components, no need to list the oligo, or the preservative -- the only really hazardous component --sodium azide.
There's a whole group of people in charge of this sort of thing. In a way, they're proud to be part of the team, keeping the rest of us safe. But sometimes, it seems to me, they're just there to get in the way. How does everyone else feel about this stuff.
Shoulda started a new thread. Oh well, I don't work in NJ anymore, anyway.
