What are three chemical properties of ibuprofen?

ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) characterized by several key chemical properties: it has a molecular formula of C13H18O2, indicating it contains two oxygen atoms, which contribute to its acidic properties. Ibuprofen is slightly soluble in water but more soluble in organic solvents like ethanol and acetone, reflecting its lipophilic nature. Additionally, it exhibits a pKa value of approximately 5, indicating it can exist in both ionized and unionized forms depending on the pH of its environment, which affects its absorption and efficacy in the body.
