C18H15F3NO2

C18H15F3NO2 is a molecular formula that denotes a class of organic compounds sharing the same atom counts but potentially differing in how those atoms are connected. As an empirical formula, it does not specify a unique structure or arrangement, so multiple constitutional isomers and stereoisomers could exist with this composition. The presence of one nitrogen and two oxygens allows for various N-containing functionalities (for example nitro groups or amide-type motifs) in combination with fluorinated substituents, often on aromatic rings. The three fluorine atoms indicate substantial fluorination, which can influence properties such as lipophilicity and metabolic stability, but the exact effects depend on the specific structure.

In practice, a molecule with this formula could belong to several structural families, including nitroaromatic compounds or fluorinated amide or ether derivatives, among other possibilities. The actual physical properties—melting and boiling points, density, solubility, and stability—depend strongly on the precise connectivity and geometry of the atoms.

The approximate molecular weight of C18H15F3NO2 is 334.3 g/mol. Without a designated structure, specific data such as X-ray crystallography, spectroscopic profiles, or reactivity cannot be assigned. Identification of a particular compound with this formula requires additional structural information, such as a SMILES string, InChI, or a CAS number. Researchers typically consult chemical databases (for example PubChem, ChemSpider, or Reaxys) to locate all isomers corresponding to this formula and to obtain validated structural and property data.
