attached you can find a spectrum I have obtained using GC-MS.
I've found traces of an unexpected substance in my product and since then I'm trying to relate the spectrum of this peak chemical structure of the substance.
My somewhat educated guess is also depicted in the spectrum. However, I'm having a hard time to explain the m/z 165 ion. I guess it might result from m/z 209 (which results from alpha cleavage) after loss of 44 (ethanal)? 165 being fluorene ion? Is it possible to definetly derive the position of the oxygen from this spectrum? Might also be attachted to the methyl group of toluene.
Any help is highly appreciated,
best regards
