Hi I am Currently working on an structure elucidation, for the compound C₇H₁₂O4.
From the current information I have I have deduced that it has 2 C=O bonds and at least one OH group. Typically I would use the H-NMR to assist with the structure but, I am confused as there are only two singlets. one occur at 2.6ppm and another at 1.3ppm. with integrals 1.5 and 2 respectively. Any help with this structure would be appreciated
