Description

1,2-Difluoro-4-(4-heptylcyclohexyl)benzene (CAS No. 139136-72-4) is a high-purity fluorinated aromatic compound with the molecular formula C₁₉H₂₈F₂. This specialty chemical features a cyclohexylbenzene core substituted with two fluorine atoms at the 1- and 2-positions and a linear heptyl chain at the 4-position of the cyclohexyl ring. The compound is supplied as a clear, colorless to pale yellow liquid with excellent thermal and chemical stability. With a molecular weight of 294.43 g/mol, it is particularly valuable in advanced material science applications due to its unique combination of fluorine substitution and alkyl chain characteristics. The product is rigorously tested for purity (typically ??97% by GC) and is packaged under inert gas to ensure long-term stability. Available in research quantities from milligrams to kilograms, this chemical is ideal for use in liquid crystal formulations, organic semiconductors, and other fluorinated material systems where precise molecular architecture is required.

Application

1,2-Difluoro-4-(4-heptylcyclohexyl)benzene serves as a key intermediate in the synthesis of advanced liquid crystal materials for display technologies, where its fluorinated aromatic core contributes to desirable dielectric anisotropy. The compound finds application in the development of low-viscosity nematic mixtures for fast-switching LCD devices, particularly in high-performance monitor and television applications. Researchers also utilize this chemical as a building block for fluorinated organic semiconductors in OLED and OFET devices, where its combination of fluorine substitution and alkyl chain promotes both charge transport and solution processability.
