trans,trans-4'-Pentyl-4-bicyclohexylmethanol TCI P2433

trans,trans-4'-Pentyl-4-bicyclohexylmethanol from TCI is a liquid crystal building block. Its trans,trans-configured bicyclohexyl core carries a pentyl chain at one end and a hydroxymethyl group at the other. It is the pentyl homologue of a similar propyl derivative. In materials laboratories, it serves as an intermediate for synthesising mesogens, which are molecules that can form liquid crystal phases. Synthesis typically goes through its primary alcohol group, for example by esterification, etherification or oxidation, to build more complex target structures.

Two structural features make this compound a preferred choice. First, the trans,trans bicyclohexyl core gives the molecule an elongated, rigid shape, which suits the formation of nematic and smectic phases in derived products. Second, the pentyl chain is longer than a propyl chain, so it generally shifts the balance between the rigid and flexible parts of the molecule. This can affect the phase temperature range and the tendency to form smectic phases. Pentyl chains are common in commercial liquid crystal molecules, so this building block is useful for research that aims to model real-world systems closely.

In Indonesia, this compound is useful for research groups in materials chemistry and physics that study liquid crystals and functional organic materials. University laboratories and research institutes can use it to prepare new mesogenic compounds, compare homologous series, and study how alkyl chain length affects phase behaviour. It also supports thesis and dissertation projects in organic synthesis that need a defined, structurally rigid alcohol intermediate as a starting point for multi-step syntheses.

• Mesogen synthesis: the primary alcohol group allows esterification or etherification to attach other molecular fragments and build liquid crystal molecules with a rigid bicyclohexyl core.
• Oxidation to aldehyde or acid derivatives: the hydroxymethyl group can be oxidised, giving access to further functional intermediates for designing liquid crystal materials.
• Homologous series studies: as the pentyl homologue of a related propyl derivative, it lets researchers compare systematically how alkyl chain length influences phase temperature ranges and smectic tendencies.
• Nematic and smectic phase research: the elongated, rigid trans,trans bicyclohexyl core makes derived products suitable for investigating how nematic and smectic phases form.
• Modelling commercial liquid crystal systems: pentyl chains are common in commercial liquid crystal molecules, so this compound helps laboratory studies reflect the structures used in practical liquid crystal materials.

Store this compound in its original, tightly closed container, in a cool, dry and well-ventilated place away from direct sunlight, heat sources and strong oxidising agents. Always check the TCI label and Safety Data Sheet for the recommended storage temperature. When handling, wear standard laboratory protective equipment: safety glasses, chemical-resistant gloves and a lab coat. Work in a fume hood or well-ventilated area, and avoid creating dust or breathing in vapours. Reseal the container promptly after use to protect the material from moisture and contamination. Dispose of waste according to local regulations and your institution's chemical waste procedures.
