Propylcyclohexane
Material direction: Saturated aliphatic hydrocarbon (cyclic alkane)
Sample & Measurement Parameters
Identification Result
87%The sample is identified as propylcyclohexane, a saturated cyclic hydrocarbon, based on a high-confidence library match (Propylcyclohexane, similarity 0.996) and the presence of characteristic aliphatic C-H stretching and bending bands. The spectrum lacks evidence for aromatic, oxygen-containing, or nitrogen-containing functional groups, confirming a pure hydrocarbon composition. The dominant bands arise from long methylene chains, consistent with a cycloalkane or linear alkane FTIR In-Depth Interpretation was not selected for this task, so this section shows the library-search result only and no deep AI interpretation was run.
Detailed interpretation
- Top library match: Propylcyclohexane #19879
- One literature source attributes the 1460 cm⁻¹ band to an aromatic group [3]; however, this conflicts with the absence of other aromatic features and the overall aliphatic character of the spectrum.
- The presence of minor branching or trace unsaturation cannot be ruled out solely from the four observed bands.
- The exact chain length and cyclic versus linear structure remain partially ambiguous, as the spectral signature is similar for long-chain alkanes and cycloalkanes.
