  • Applications

    Pentylcyclohexane (CAS 4292-92-6) is a hydrophobic, near‑nonpolar saturated cyclic hydrocarbon used primarily as a nonpolar solvent/diluent in organic synthesis, coating, ink, and adhesive formulations; as the organic phase for extraction and purification of poorly polar compounds and as a hydrophobic carrier in emulsions; in analysis and research it serves as a reference hydrocarbon or matrix component for chromatographic and thermophysical measurements, as a representative alkylcyclohexane in gasoline/jet‑fuel surrogate blends to study combustion kinetics, emissions, and ignition quality, and as a model substrate for catalyst evaluations (hydrocracking, isomerization, mild oxidation) and materials stability; owing to its relatively high boiling point and chemical inertness, Pentylcyclohexane also functions as a robust apolar medium for reactions and lab–pilot processing, and as a solvent for hydrophobic additives/actives in certain specialized formulations.
