TCI M3152 1-Methoxy-4-(trans-4-propylcyclohexyl)benzene is a phenylcyclohexane compound that joins a methoxy-substituted benzene ring to a propyl-substituted cyclohexane ring in the trans configuration. This rigid, rod-shaped structure is a classic motif in materials chemistry, particularly as a building block and component for liquid crystal materials and other functional organic compounds. In the laboratory it serves as a starting material for the synthesis of further derivatives through reactions on the aromatic ring, and equally as a reference compound in studies of the relationship between molecular structure and mesomorphic behaviour.
The property that makes this compound a preferred choice is the trans geometry of the cyclohexane ring, which ensures that both substituents occupy equatorial positions, producing a straight molecule that packs readily in parallel alignment. This regularity is a prerequisite for the formation of mesomorphic phases, and it also makes the compound straightforward to purify by recrystallisation. The methoxy group on the aromatic ring is electron-donating, so it activates the ring toward electrophilic substitution while simultaneously providing a handle for demethylation to the corresponding phenol — a gateway to a wide range of further derivatives.
In Indonesian laboratories this material is typically used in university and institutional research settings working on materials chemistry and organic synthesis, where a well-defined rod-like intermediate is needed as a reliable starting point. It is handled at bench scale for derivative preparation, structure–property studies, and as a comparison standard when characterising new mesogenic candidates. The TCI packaging format suits research-scale consumption rather than production use.

Store the container tightly closed in a cool, dry, well-ventilated area, away from direct sunlight, heat sources, and any strong oxidising agents. Keep the material in its original supplier container or in a compatible tightly sealed glass bottle, and label any transferred portion clearly with the compound name and CAS number. Handle in a fume hood using standard laboratory personal protective equipment — safety glasses, gloves, and a laboratory coat — and avoid the generation of dust or aerosols. Allow refrigerated containers to reach room temperature before opening to prevent moisture condensation, and always consult the manufacturer's safety data sheet before first use and for full disposal guidance.
