4,4′-Oxydianiline CAS 101-80-4

What is 4,4′-Oxydianiline CAS 101-80-4?

4,4′-Oxydianiline CAS 101-80-4 is an aromatic diamine consisting of two aniline groups connected by an ether linkage. It typically appears as a white crystalline solid or beige powder. Due to the presence of two amino functional groups and an aromatic ether backbone, it serves as an important monomer and intermediate for high-performance polymer materials and specialty chemicals.

Specifications

Features

• Aromatic Diamine Structure: Contains two primary amine groups linked through an ether bridge, enabling smooth condensation polymerization and crosslinking reactions.
• High Thermal Stability: Exhibits a high melting point and a stable aromatic backbone, crucial for processing high-temperature polymer systems.
• Low Water Solubility: Insoluble in water but highly compatible with dipolar aprotic organic solvents (such as NMP, DMF, and DMAc) used in polymer processing.
• Stable Solid Form: Typically obtained as a white crystalline solid or powder suitable for long-term industrial storage and handling.

Applications

• Polyimide Resin Production: Acts as an indispensable primary monomer (often reacted with pyromellitic dianhydride, PMDA) to manufacture high-performance polyimide films (e.g., Kapton), fibers, and engineering plastics with outstanding thermal and mechanical profiles.
• High-Performance Polymers: Extensively utilized in the polycondensation synthesis of advanced polyesterimide resins, poly(amide-imide)s, and liquid crystalline polymers.
• Insulating Materials: Applied as a vital component in high-temperature wire enamels, insulating varnishes, and protective coatings for extreme-environment electrical and aerospace systems.
• Specialty Chemical Intermediate: Serves as a versatile structural intermediate for specialized azo dyes, organic pigments, and advanced functional materials research.
