Hi there,
I have a question regarding a chemical produced by two different manufacturers, both of which claim it to be the structure seen in this image.
One of the NMRs is attached as a PDF, the other is inset.
To me, the one in the inset does not look like the same structure, but the PDF Does seem to match.
However, I am no NMR expert. My knowledge is very limited. Yet this seems fairly obvious.
Would anyone with some expertise here care to comment on the differences between these two NMRs?
