URGENT Can you please help me identify an organic compound

[yoyodude91]

I've been working on this for a long time and cannot figure out what the compound is. Whenever I think I figured it out (the NMR has been what I've looked at the most when trying to figure it out), I look up the compound and see that its standard NMR is completely different from mine. If anyone has any ideas or any advice on how I can come closer to figuring this out, I would really appreciate it.

-It's a clear liquid with a strong smell.
-pH = 4.
-I calculated density to 0.983.
-refractive index is around 1.498 (when i took it, the value was between 1.490 and 1.500. It was closer to 1.500).

A picture of the IR is on the following link:

Thank you.

Would you mind digitizing your IR measurement?

And another question: Does it form a film?

[Don_Hilton]

first step in solving an unknown: History. can you give any indication of what kind of sample this is? Is it a natrual product, a reaction product, distillation cut, product purchased at the store, unknown from analytical chemistry class? How was it derived?

How do you know that it is a pure compund? have you run GC, LC, TLC, other separation technique?

Do you have elemental composition for this? Or have you done an ash test to see if it will leave a residue?

You say this is pH 4: What conncentration was this in water? Or how did you measure the pH?

Do you have a list of solvents in which the compound is soluable or insoluable?

Other questions come to mind - but without knowing a bit of history to allow us to rule thiings out, we are having to select approaches that include all the kinds of chemical compunds in the world. If this is something that comes from a lipid fraction in a fish, for instance, the range of compounds drops considerably...

OK so what do you think you have? Have you done a D2O shake? I'm very rusty but I'd say you have a subsitituted phenol, maybe with a vinyl type group. I can't view the IR at all, it's miniature

WRT your NMR, what was the solvent used?

[unmgvar]

it would help some of us mainly you for sure, to have the mass as well.
do you have the information?
