H-NMR of benzoyl pyridine

emrebjk - 15-1-2007 at 03:35

Hi all. I bought benzoylpyridine from merck. But I need it's H-NMR spectrum. if you have a NMR atlas can you send it to me. Also if you send 2-acetylpyridine and 2-pyridinecarboxyaldehyde I will be so happy :) THANX

Don't any of the usual suspects (Aldrich, Fluka) give that away online, cf. on pages of the compounds in question in their online catalog?

How about NIST?

Finally, how about a software NMR emulator? Structure to spectrum? I have seen such things.

Here is FT-NMR of 2-benzoylpyridine from Aldrich web site

3- and 4-benzoylpyridines also available.

Here's FT-NMR of 2-acetylpyridine from same source

and finally 2-pyridinecarboxaldehyde FT-NMR from same Aldrich site:


Don't mention it. I just requested three journal articles and this is my atonement.

My karmic balance is maintained.

(Fat chance!)

thank you too much

If you need IR, NMR, UV/VIS spectra.... this is the place to go. Just about every basic organic compound can be found here. I used this during organic 1 and 2 along with the lab, this is a very good resource.

One problem with those Aldrich spectra is that the filename is not meaningful, as such just a code number and the name or structure does not appear in the image anywhere I could see. You might want to edit those in for future use.

I'm feeling greedy so I'd like to know if you (or anyone else here) has a similar database of UV/vis spectra?

Dr. Beaker - 15-1-2007 at 12:47

if you got chemdraw there's an option there to get proton and carbon NMR to the structure you enter. naturally, it's just a rough aproximation, but is better then nothing. it will generally give good results for simple organic compounds though,
there are more proffessional apps for this, the NMR guys at my U know them better, and they're really accurate.

I think ACD labs H-NMR prediction software is better than chem office.

Sorry, I do not. However, If i come across anything in my searches, I will post. The link I provided does have UV/vis spectra, however it is hit or miss.

Chemdraws H-NMR prediction is pretty bad. You need really specialized software if you want to get anything meaningful for more complicated compounds.

Well here are the ones I know and use

PubSpectra (a bit chaotic, but huge)

USC (only a view substances)

and
fluorophores

Hope you can use some of those...

yeah , this is of best sites about IR and NMR...i used to query it in my uni spectroscopy course...and its very reliable :cool:

I have most of the olde-skule UV-Vis Atlas in hard copy (the old onion skin paper). If someone really needs it, I could look it up, scan it in and zip you a .pdf.

Best,
