Comments:

FindIt identifies the correct structure at its top position for molecular formula and proton results. The carbon spectrum recycle time was chosen too short to observe its 148.8 ppm resonance. Due to this missing resonance, the correct structure using the proton and carbon analysis results obtains only FindIt place 70.
