The ordinary FTIR evidence does not support a firm identification of this sample as N-(4-ethoxy-2-hydroxyphenyl)acetamide. The library search returned that compound as the nominal top hit, but all reported similarities are 0.000 and the top-15 candidates are chemically inconsistent with one another. The measured spectrum is better described conservatively as a substituted aromatic organic material showing alkyl C-H bands and fingerprint-region absorptions consistent with possible C-O or other heteroatom-containing functionality, but without enough direct evidence to assign a specific compound or narrow chemical subclass confidently
