Each has a strong peak near 1689 cm-1 due to stretching of the C=O bond of the acid group [-(C=O)-O-H]. The two substances have many structural features in common, resulting in similar peaks of their spectra. Formula and structure: The acetylsalicylic acid chemical formula is C 9 H 8 O4 and the extended formula is CH 3 COOC 6 H 4 COOH. Aspirin is one of the most frequently used and cheapest drugs in medicine. These groups of atoms contain oxygen or nitrogen or sometimes sulfur attached to a hydrocarbon skeleton. Observe the color: Pure aspirin would show no color, while salicylic acid or traces of it in impure aspirin will show a purple color. A carboxyl group (COOH) is a functional group consisting of a carbonyl group (C=O) with a hydroxyl group (O-H) attached to the same carbon atom. Examine the aspirin crystals under a microscope.
