Figure 2. 13 C DEPT NMR spectrum of Ibuprofen, 2M in CDCl 3 with TMS, 12 scans with 1 Hz line broadening, total acquisition time, 3 minutes. Before humans had the luxury of pain relievers and pharmaceutical drugs, many relied on the curing effects of willow tree bark, which was either chewed or boiled and used to relieve fevers and inflammation. Ibuprofen (C15H18O2) is an anti-inflammatory drug. Since most organic compounds have these features, these C-H vibrations are usually not noted when interpreting a routine IR spectrum. 1 H NMR spectrum of Ibuprofen, 2M in CDCl 3 with TMS, 1 scan with no signal enhancement. Chemical Concepts, A Wiley Division, Weinheim, Germany. Aspirin, acetylsalicylic acid, is a familiar drug, used for relieving cold and flu symptoms, fevers, and general aches and pains in the body, and, as made clear by its chemical formula, contains salicin a chemical found in willow bark. The hybridization of the carbon affects the exact position of the It is a pharmacologically effective enantiomer of racemic ibuprofen that differs in physicochemical properties.
