Description

1,2,4-Triphenylbenzene CAS NO 1165-53-3 is a high-purity, polycyclic aromatic hydrocarbon (PAH) compound characterized by its three phenyl groups attached to a central benzene ring. This unique molecular structure makes it a valuable organic intermediate and building block for advanced materials research and synthesis. It is primarily utilized by pharmaceutical R&D laboratories, OLED material scientists, and specialty chemical manufacturers for developing novel compounds and functional materials.

Application

• Organic Light-Emitting Diode (OLED) Materials: Serves as a core building block or host material in the synthesis of advanced electroluminescent compounds for display and lighting technologies.
• Pharmaceutical Intermediates: Used in the research and development of active pharmaceutical ingredients (APIs) and other complex organic molecules.
• Liquid Crystal (LC) Materials: Acts as a precursor or a component in the synthesis of liquid crystalline compounds for electronic displays.
• Organic Semiconductor Research: Employed as a model compound or a starting material in the development of organic field-effect transistors (OFETs) and photovoltaic materials.
• Chemical Synthesis & Catalysis: Functions as a ligand in catalytic systems or as a rigid scaffold in supramolecular chemistry and metal-organic frameworks (MOFs).
• Analytical Reference Standard: Used as a high-purity standard in chromatography (HPLC, GC) for the identification and quantification of similar aromatic compounds in environmental or material analysis.
