C7H9NO2S

C7H9NO2S is the molecular formula representing seven carbon atoms, nine hydrogen atoms, one nitrogen atom, two oxygen atoms, and one sulfur atom. It corresponds to a family of organic isomers rather than a single compound, meaning that multiple distinct structures can share this same formula. The exact properties of any particular compound with this formula depend on how the atoms are connected and what functional groups are present.

The nominal molecular mass is approximately 171.22 g/mol. In analytical contexts, this formula is used to identify candidate structures in mass spectrometry and to search chemical databases. Different isomers with the same formula will have different physical properties, such as boiling point, melting point, and density, as well as distinct spectroscopic signatures.

Because several structural possibilities exist for C7H9NO2S, one cannot determine a compound’s properties or reactivity without a specific structural specification, such as a systematic name, SMILES string, or InChI. If a particular isomer is identified, its synthetic accessibility, functional reactivity, and potential applications would be determined by that structure.

In summary, C7H9NO2S denotes a set of related organic compounds defined by their elemental composition. Identification and study of any specific member require explicit structural information, while the formula itself serves as a compact descriptor used in databases, spectrometry, and theoretical discussions of isomerism.
