1,2,3,4-Cyclobutanetetracarboxylic1,2,3,4-dianhydride CBDA CAS 4415-87-6
CBDA CAS 4415-87-6 for Transparent and Low-Dielectric Polyimide Synthesis
1,2,3,4-Cyclobutanetetracarboxylic dianhydride, commonly known as CBDA, is a cycloaliphatic dianhydride monomer used as a structural building block in transparent, low-color and low-dielectric polyimide synthesis. Its compact alicyclic structure makes CBDA relevant to polymer systems where optical clarity, reduced coloration, dielectric behavior, flexibility and thermal performance need to be balanced.
CBDA belongs to the broader category of polyimide dianhydride monomers and is also included in Aure Chemical’s Polyimide Monomers: Diamines and Dianhydrides technical guide. It is often considered in optical, transparent, electronic-grade, flexible film and specialty polyimide material development, depending on the paired diamine, formulation and processing conditions.

Key Features in Polyimide Design
Cycloaliphatic dianhydride structure, relevant to transparent and low-color polyimide dianhydride monomers.
Compact alicyclic structure may help reduce charge-transfer interactions and support optical clarity depending on the paired diamine and polymer architecture.
Non-aromatic dianhydride design may be considered when low coloration, dielectric behavior and transparent film performance are part of the target material design.
CBDA can be considered in optical and transparent polyimide systems where reduced coloration and optical clarity are important.
Final material properties depend on dianhydride purity, diamine selection, solvent system, imidization conditions, film formation and polymer processing method.
Pairing CBDA with Diamine Monomers
In polyimide synthesis, CBDA may be evaluated with selected monomers from Aure Chemical’s polyimide diamine monomers supply portfolio to design transparent, low-color, low-dielectric and flexible PI systems. Fluorinated diamines such as TFMB / TFDB CAS 341-58-2 may be considered when optical clarity, dielectric behavior or reduced moisture uptake are part of the target polymer design.
Ether-containing diamines such as BAPP CAS 13080-86-9 or TPE-Q CAS 3491-12-1 may help adjust solubility, flexibility and film-forming behavior, while rigid aromatic diamines may be selected when dimensional stability and mechanical strength are more important.
Application Context of CBDA in Polyimide Systems
CBDA is typically used as a structural dianhydride monomer rather than a finished application material. It is commonly discussed in transparent, low-color, low-dielectric and flexible polyimide material development, where alicyclic dianhydride structure can influence optical properties, charge-transfer behavior and polymer morphology.
Optical and transparent polyimide systems – monomer selection for reduced coloration, optical clarity and transparent film design.
Electronics and microelectronics polyimide applications – low-dielectric, insulation and electronic material requirements.
Flexible films, coatings and adhesives – flexible, transparent and processable PI material systems.
Energy storage and separation applications – functional polymer and membrane-related research contexts.
Specialty functional polyimide materials – alicyclic dianhydride selection for advanced polymer research and formulation design.
