your mind
A manufacturer provided me with the following analysis HPCL and HNMR. Can anybody help me read them?
Thanks in advance! :)

Purity on HPLC: 99.2 %

NMR peaks (wich was performed in DMSO):
10.6 - 1 H for the aromatic amine
between 7.2 and 6.8 - 4 aromatic H
3.7 - 3 H for the methoxy
3.4 - residual peak of water (surely from the DMSO vial)
near 2.7 - 1 H for the tertiary carbon ( N-CH-(CH3)2)
between 2.65 and 2.55 - two time 2 H for the "ethyl chain"
near 2.5 - residual peak of the solvent (wich is DMSO)
2.2 - 3 H for the methyl (CH3-N)
0.96 - 6 H for the two methyl ((CH3)2-CH-N)

So, if your product corresponds to this analysis, it seem to be pretty pure.
But some inorganic salts could be present and wouldn't be detected (I think it's unlikely).
I hope I am right.
Sorry or my poor English.
If you need more information, let me know.
 
I think it looks good, but a manufacturer can send you anything they want. If this was coming from your personal GC/NMR lab then I could say with good faith that this is pure compound.
 
The HPLC chromatogram appears to be an absorbance trace for the 254.4 nm wavelength. Granted, any likely impurities or contaminants would show appreciable absorbance at 254.4 nm, but in principle, the product could still be cut to fuck with something which lacks chromophores absorbing at 254.4 nm. With an HPLC-DAD you basically see what you're looking for, and the peak at 9.501 min could be anything, really. Any organic cuts or residual solvents present at high enough levels would show up in the NMR spectrum, but inorganic salts would not.

I'd like to see a mass spectrum and a GC-MS or LC-MS TIC, but even then you're blind to inorganic contaminants. The product could contain toxic levels of e.g. cadmium or cyanide salts and you wouldn't even have a clue.

The big question is whether you trust your Chinese friends.
