Description

Benzoic Acid, 4,4'-[(2,5-Dimethoxy-1,4-Phenylene)Di-(1E)-2,1-Ethenediyl]Bis- is a high-purity, specialized organic compound featuring a conjugated bis-stilbene core functionalized with benzoic acid groups. This unique molecular architecture makes it a valuable advanced intermediate or functional monomer for synthesizing sophisticated materials. It is primarily sought by R&D laboratories and specialty chemical manufacturers working in areas such as organic electronics, photoresists, and advanced polymer systems.

Application

• Organic Electronic Materials: Serves as a key building block for conjugated polymers and small molecules used in Organic Light-Emitting Diodes (OLEDs), Organic Photovoltaics (OPVs), and Field-Effect Transistors (OFETs).
• Photoactive Polymers: Used in the synthesis of polymers for advanced photoresists, photoalignment layers in liquid crystal displays, and other light-sensitive coatings.
• Specialty Monomers: Acts as a difunctional monomer for creating polyesters, polyamides, or other polymers with built-in chromophores and specific optical properties.
• Nonlinear Optical (NLO) Materials: Investigated as a precursor for materials with second- or third-order nonlinear optical effects due to its extended π-conjugated system.
• Chemical Research & Development: Employed as a standard or intermediate in academic and industrial research focused on novel organic semiconductors and functional dyes.
• Liquid Crystal Synthesis: Potential use as a rigid, aromatic core component in the design of novel liquid crystalline materials.

Quality Control

Our production of this advanced intermediate adheres to strict quality protocols to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical techniques including HPLC, NMR, and FT-IR. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with each shipment to support your R&D and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its acid functionality, keep away from strong bases and oxidizing agents. For long-term storage, consider an inert atmosphere to preserve stability.
