1,1,1-Tris(4-hydroxyphenyl)ethane (CAS 27955-94-8), commonly abbreviated as THPE, is a premium trifunctional phenolic branching agent. In Elemental Derivatives hierarchy (Oxygen/Phenolic path), it represents a structural "node" used to transform linear polymers into complex, high-performance 3D networks. THPE's unique "tri-pod" molecular architecture allows it to act as a precision branching point in the synthesis of Polycarbonates and Epoxy Resins. By introducing controlled branching, THPE significantly elevates the glass transition temperature (Tg), mechanical toughness, and chemical resistance of materials. For CDMOs and Specialty Chemical buyers, THPE is often viewed as the "safer" and more functionally capable alternative to standard bisphenols when designing hyperbranched systems for aerospace and high-density electronics. We are a globally established THPE supplier by having End to END formulator capabilities and various other intermediates and fine chemicals worldwide through comprehensive regulatory documentation (CoA), traceability, and consistent global supply capabilities, ensuring reliable lead times and quality assurance across all grades.
