Description

4,4'-[(2-Formy-1,4-Phenylene)Bis(Oxymethylene)]Bis-Cyclohexane Carboxylic Acid is a high-purity, functionalized organic building block featuring a central aromatic dialdehyde core symmetrically linked to two cyclohexanecarboxylic acid groups via ether bridges. This unique molecular architecture makes it a critical intermediate for synthesizing advanced polymers, liquid crystals, and pharmaceutical active ingredients. It is essential for R&D and production chemists in the fine chemical, advanced material, and life science sectors seeking to develop novel compounds with tailored properties.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs), particularly those requiring rigid, symmetrical scaffolds.
• Liquid Crystal Materials: Used in the development of novel liquid crystal compounds for display technologies, leveraging its rigid-rod structure and functional groups for mesogen synthesis.
• Polymer & Resin Synthesis: Acts as a monomer or cross-linking agent for producing high-performance polyesters, polyamides, and epoxy resins with enhanced thermal and mechanical properties.
• Metal-Organic Frameworks (MOFs): Functions as an organic linker in the construction of MOFs for gas storage, separation, and catalysis applications.
• Dendrimer & Hyperbranched Polymer Core: Utilized as a central core unit for building symmetrical dendrimers and polymers in advanced material science.
• Organic Synthesis Building Block: Employed in academic and industrial research for constructing complex molecular architectures via reactions at its aldehyde and carboxylic acid functional groups.

Quality Control

Our production of 4,4'-[(2-Formy-1,4-Phenylene)Bis(Oxymethylene)]Bis-Cyclohexane Carboxylic Acid adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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). The compound may be light-sensitive and hygroscopic; therefore, containers should be kept sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent oxidation and moisture uptake.
