Product Details

AB-TFMB CAS 1449757-11-2 for Fluorinated Polyimide Synthesis

N,N'-(2,2'-Bis(trifluoromethyl)-[1,1'-biphenyl]-4,4'-diyl)bis(4-aminobenzamide), commonly known as AB-TFMB, is a fluorinated amide-containing diamine monomer used as a structural building block in high-performance polyimide and specialty polymer synthesis. Its rigid biphenyl core, trifluoromethyl groups and amide linkages make AB-TFMB relevant to polyimide systems where thermal behavior, optical performance, dimensional stability, dielectric properties and gas transport behavior need to be balanced.

AB-TFMB belongs to the broader category of polyimide diamine monomers and is also part of Aure Chemical’s polyimide diamine monomers supply portfolio. It is often considered in fluorinated, transparent, dielectric and specialty functional polyimide material development, depending on the paired dianhydride, formulation and processing conditions.

Key Features in Polyimide Design

Fluorinated aromatic diamine structure, relevant to fluorinated polyimide diamine applications.
Trifluoromethyl groups may help reduce polarizability and influence dielectric behavior depending on the paired dianhydride and polymer design.
Rigid biphenyl framework may support dimensional stability and chain rigidity in selected polyimide systems.
Amide linkages may influence intermolecular interactions, hydrogen bonding, gas transport behavior and mechanical performance depending on the full polymer architecture.
Final material properties depend on monomer purity, dianhydride selection, solvent system, imidization conditions and polymer processing method.

Pairing AB-TFMB with Dianhydride Monomers

In polyimide synthesis, AB-TFMB may be evaluated with selected polyimide dianhydride monomers to design fluorinated, transparent, dielectric and specialty functional PI systems. Fluorinated dianhydrides such as 6FDA CAS 1107-00-2 may be considered when optical, dielectric or moisture-related properties are part of the target polymer design.

Rigid aromatic dianhydrides such as BPDA CAS 2420-87-3 or BTDA CAS 2421-28-5 may support thermal resistance and dimensional stability, while ether-containing dianhydrides such as ODPA CAS 1823-59-2 may help adjust processability and film-forming behavior.

Application Context of AB-TFMB in Polyimide Systems

AB-TFMB is typically used as a structural diamine monomer rather than a finished application material. It is commonly discussed in fluorinated, transparent, dielectric and specialty functional polyimide material development, where trifluoromethyl groups, amide linkages and rigid aromatic structure can influence polymer performance.

Fluorinated polyimide diamine applications – monomer selection for fluorinated PI systems.
Optical and transparent polyimide applications – optical clarity, reduced coloration and polymer structure considerations.
Electronics and semiconductor polyimide applications – dielectric, insulation and electronic material requirements.
Specialty functional polyimide applications – gas transport behavior, structural rigidity and advanced polymer research contexts.

COA, SDS and Technical Documentation

Aure Chemical can provide COA, SDS, TDS, typical specifications and packaging information for AB-TFMB CAS 1449757-11-2 upon request. Since AB-TFMB is a fluorinated amide-containing diamine monomer, final purity, appearance and batch-specific data should be confirmed by the latest COA before order confirmation.

Please share the required purity, target specification, quantity, destination country or port, preferred packaging method and required documents so we can review availability, documentation support and export packing options.
