Description

2,2′-((3,3′,5,5′-Tetramethyl-(1,1′-biphenyl)-4,4′-diyl)-bis(oxymethylene))-bis-oxirane (CAS No. 85954-11-6) is a high-purity biphenyl-based epoxy compound with the molecular formula C₂₂H₂₆O₄. This specialized chemical features a symmetrical structure with two epoxy-functionalized oxymethylene bridges attached to a tetramethylbiphenyl core, offering excellent thermal stability and reactivity for advanced polymer synthesis. Ideal for researchers developing high-performance epoxy resins, adhesives, or composite materials requiring controlled cross-linking density. Supplied as a crystalline solid with >95% purity (HPLC), this compound is rigorously tested by GC-MS and ¹H NMR to ensure batch-to-batch consistency. Store under inert atmosphere at 2-8°C to maintain stability of the epoxy groups.

Application

This tetramethylbiphenyl diepoxide serves as a critical monomer for synthesizing high-T_g epoxy resins used in aerospace composites and electronic encapsulants. The sterically hindered structure enhances thermal resistance in cured networks while maintaining processability. Researchers utilize it to develop low-dielectric materials for 5G applications and as a crosslinker for specialty adhesives requiring dimensional stability under thermal cycling.
