C13H18O2
C13H18O2 represents a chemical formula indicating a molecule composed of 13 carbon atoms, 18 hydrogen atoms, and 2 oxygen atoms. Without further information, the formula is insufficient to identify a specific compound as many different molecules can share the same chemical formula. Isomers, which are molecules with the same chemical formula but different structural arrangements of atoms, are common. Therefore, C13H18O2 could refer to a variety of organic compounds exhibiting distinct properties. To identify the specific compound, further information such as its structural formula, IUPAC name, physical properties (e.g., melting point, boiling point), spectroscopic data (e.g., NMR, IR), or known uses would be required. The compound's class (e.g., ester, carboxylic acid, ketone) would also be helpful in narrowing down the possibilities.
