Description

2,2',4,4'-Quaterphenyl Tetracarboxylic Acid is a high-purity, multi-functional aromatic carboxylic acid building block of significant interest in advanced material science. Its rigid, conjugated structure and multiple reactive sites make it a critical precursor for synthesizing high-performance polymers and organic electronic components. This compound is essential for researchers and manufacturers in the fields of liquid crystal polymers (LCPs), polyimides, and organic semiconductors, where precise molecular architecture dictates material properties.

Application

• Liquid Crystal Polymer (LCP) Monomer: A key raw material for producing high-temperature, high-strength LCPs used in electronics, automotive, and aerospace components.
• Polyimide Synthesis: Serves as a tetracarboxylic acid monomer for creating advanced polyimide films and coatings with exceptional thermal stability and mechanical strength.
• Organic Semiconductor Precursor: Used in the development of organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and thin-film transistors (TFTs).
• Metal-Organic Framework (MOF) Linker: Its multiple carboxylate groups enable the construction of complex, porous MOF structures for gas storage, separation, and catalysis.
• Pharmaceutical Intermediate: Employed in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs) requiring rigid, polyaromatic cores.
• Dye and Pigment Chemistry: Acts as a foundational structure for creating specialized dyes and high-performance pigments.

Quality Control

Our 2,2',4,4'-Quaterphenyl Tetracarboxylic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using a desiccator or an inert atmosphere.
