A Chem237 student who shall remain nameless noticed one day that his shaving cream had a taste component that reminded him of the taste of his favorite El Cheapo yogurt. Ethyl acetate extracts of both materials produced a substance that almost did not run at all on a silica TLC plate with toluene as the eluent. He was able to distill a small amount of the material at 8 mm Hg pressure and observed a boiling point of 136 °C at that pressure. However, the material solidified in the condensor of his still and had to be removed mechanically. Elemental analysis of the solid suggested the composition C9H10O3. The solid melted at 117 °C and gave the following nmr spectra and the ir spectrum. What is this material and why and how did it come to be in both of these sources?
