For professionals in chemical synthesis, research, and industrial applications, selecting the right solvent is critical. Methylcyclohexane (CAS 108-87-2) and Cyclohexane are both alicyclic hydrocarbons with similar structural bases, but their methyl substituent imparts distinct properties that influence their suitability for different tasks. This comparison aims to help chemical users and procurement managers understand the nuances between these two compounds and make informed decisions when purchasing.

Structural and Property Differences

The fundamental difference lies in their chemical structure. Cyclohexane (C6H12) is a simple cyclic alkane. Methylcyclohexane (C7H14) is its derivative, featuring a methyl group (-CH3) attached to the cyclohexane ring. This seemingly small addition has notable effects:

  • Polarity: Both are non-polar solvents.
  • Boiling Point: Methylcyclohexane has a higher boiling point (approx. 101°C) than Cyclohexane (approx. 80.7°C). This means Methylcyclohexane is less volatile and can be used in reactions requiring higher temperatures or extended reaction times without significant solvent loss.
  • Melting Point: Methylcyclohexane has a lower melting point (-126.3°C) compared to Cyclohexane (-94.6°C), though both remain liquid under typical laboratory conditions.
  • Density: Methylcyclohexane (approx. 0.77 g/mL) is slightly denser than Cyclohexane (approx. 0.779 g/mL).
  • Solubility: Both are excellent solvents for non-polar organic compounds. However, the presence of the methyl group in Methylcyclohexane can subtly alter its solvency for certain complex molecules.

When deciding whether to buy Methylcyclohexane or Cyclohexane, consider the specific reaction temperature and the required volatility of your solvent system. As a manufacturer, we ensure both high-purity Methylcyclohexane and Cyclohexane are available to meet diverse client needs.

Applications in Synthesis and Industry

Both compounds are valuable in organic synthesis and as industrial solvents. However, their differing boiling points often dictate their use:

  • Methylcyclohexane (CAS 108-87-2): Its lower volatility makes it a preferred choice for reactions that need to be run at elevated temperatures or for longer durations. It's also noted for its use in jet fuel formulations and as a component in certain industrial cleaners. Researchers often use it in studies requiring stable, higher-temperature non-polar environments.
  • Cyclohexane: Its higher volatility and lower boiling point make it suitable for applications where rapid evaporation is desired, such as in certain chromatography techniques or in the production of Nylon precursors (adipic acid and caprolactam). It is also a common solvent in organic synthesis, particularly for reactions that proceed efficiently at lower temperatures.

For procurement managers, understanding these application-specific advantages is key. If your process involves high-temperature reactions, seeking a Methylcyclohexane manufacturer for supply is advisable. For lower-temperature or rapid-evaporation needs, Cyclohexane might be the better choice. We offer competitive pricing for both, so requesting a quote for either compound is a good starting point.

Comparative Sourcing Strategy

When deciding to buy Methylcyclohexane or Cyclohexane, consider these sourcing factors:

  • Purity Requirements: Both are available in various grades. Ensure the purity specified by the manufacturer meets your application's needs.
  • Volume: Whether you need small research quantities or bulk industrial volumes, reliable manufacturers can accommodate your demands.
  • Supplier Reputation: Partnering with experienced suppliers who provide comprehensive documentation (CAS numbers, SDS, COA) is crucial for both compounds.
