Description

2,2'-[[1,1'-Biphenyl]-4,4'-Diylbis(Oxy)]Bisethanol is a high-purity organic compound featuring a biphenyl core symmetrically substituted with ethoxyethanol groups. This structure makes it a valuable versatile intermediate and monomer for the synthesis of advanced polymers and specialty chemicals. It is primarily sought after by manufacturers in the pharmaceutical, polymer, and liquid crystal industries for its role in creating materials with specific optical and mechanical properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring a rigid, aromatic linker with hydrophilic terminal groups.
• Polymer & Resin Synthesis: Serves as a key monomer or chain extender for producing polyesters, polycarbonates, and epoxy resins, enhancing thermal stability and mechanical strength.
• Liquid Crystal Materials: Acts as a core building block for mesogenic compounds used in display technologies (LCDs) due to its rigid biphenyl structure and functionalizable ends.
• Crosslinking Agent: Employed in coatings, adhesives, and sealants to improve network density, chemical resistance, and durability.
• Organic Synthesis Intermediate: Utilized in research and fine chemical production for constructing complex molecules, including dendrimers and macrocycles.
• UV Absorber / Stabilizer Precursor: A starting material for synthesizing additives that protect polymers from photodegradation.

Quality Control

Our 2,2'-[[1,1'-Biphenyl]-4,4'-Diylbis(Oxy)]Bisethanol is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment. We can support compliance requirements for cGMP and other relevant regulatory frameworks upon request.

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 hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
