Description

3,3'-(1,4-Phenylene)Dipropan-1-Ol is a bifunctional organic compound featuring a central phenylene core symmetrically substituted with propanol chains. This structure makes it a valuable versatile building block and intermediate in advanced organic synthesis. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the production of active pharmaceutical ingredients (APIs), particularly for compounds requiring rigid, aromatic spacers with terminal hydroxyl functionality.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators where its diol structure can be leveraged to create specific bioactive molecules.
• Polymer & Resin Modifier: Acts as a chain extender or cross-linking agent in the synthesis of polyurethanes, polyesters, and epoxy resins, enhancing material properties like toughness and thermal stability.
• Liquid Crystal & OLED Materials: Functions as a core component in the synthesis of monomers for liquid crystalline polymers and organic light-emitting diodes (OLEDs) due to its rigid-rod molecular geometry.
• Organic Synthesis Building Block: Employed in various coupling reactions (e.g., esterification, etherification) to create symmetric ligands, dendrimers, and macrocyclic compounds.
• Cosmetic & Personal Care Ingredients: Potential intermediate for UV absorbers, antioxidants, and emollients in high-performance cosmetic formulations.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which may affect product quality. Keep away from strong oxidizing agents.
