Industrial Applications of 4,4-BIS(3-AMINOPHENOXY)BIPHENYL(43BAPOBP)
| Industry | Application | Process |
|---|---|---|
| High-Performance Polymers | Monomer for polyimide synthesis, used to produce high-temperature-resistant and high-dielectric polyimide films and resins | Reacted with dianhydrides (e.g., pyromellitic dianhydride, biphenyl tetracarboxylic dianhydride) via condensation polymerization followed by thermal or chemical imidization to produce polyimide |
| Electronic Encapsulation Materials | Critical diamine monomer for polyimide base films in flexible copper-clad laminates (FCCL), enhancing dimensional stability and solder resistance | Used as a diamine component in the synthesis of polyimide precursors (polyamic acid), followed by coating, drying, and imidization to form films |
| Aerospace Composites | Modified monomer for high-temperature structural adhesives and prepreg resins | Incorporated to introduce rigid biphenyl and ether linkages, improving resin glass transition temperature (Tg) and thermo-oxidative stability |
| Liquid Crystal Alignment Agents | Specialized diamine monomer for polyimide alignment layers in liquid crystal displays (LCDs) | Copolymerized with tetracarboxylic dianhydrides to form photo-alignable polyimide; liquid crystal molecular orientation is achieved via ultraviolet irradiation |
Manufacturing Quality Control of 4,4-BIS(3-AMINOPHENOXY)BIPHENYL(43BAPOBP)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine-based reagent to determine water content based on stoichiometric reaction with iodine and sulfur dioxide. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C in a platinum crucible and measuring non-volatile inorganic residue as mass percentage. |
| Heavy Metals | ICP-OES | Multi-element detection after acid digestion; quantification via calibration curves using emission intensities at element-specific wavelengths. |
| Chloride Content | Ion Chromatography | Separation of chloride anions on an anion-exchange column with conductivity detection, referenced to sodium chloride standard. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample with sulfuric acid followed by heating to constant weight to determine inorganic sulfate-derived residue. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range over which solid transforms to liquid. |
| Solubility in Common Solvents | Visual Observation | Qualitative assessment of complete dissolution in specified solvents (e.g., DMF, THF) at defined concentrations and temperatures. |
| Bulk Density | USP <616> Tap Density Method | Mass per unit volume measured after controlled tapping of a known mass in a calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered light intensity patterns from dispersed particles to calculate size distribution based on Mie theory. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using a calibrated glass electrode pH meter. |
