Industrial Applications of 1,3-Bis(2,4-diaminophenoxy)propane tetrahydrochloride
| Industry | Application | Process |
|---|---|---|
| Electronic Chemicals | Alignment layer component for liquid crystal displays (LCDs) | Used as a polyimide precursor; copolymerized with dianhydrides to form alignment films, which are applied via coating, pre-baked, and thermally cured to generate liquid crystal molecular alignment layers |
| Electronic Chemicals | Modifier for organic light-emitting diode (OLED) encapsulation materials | Incorporated into epoxy or silicone-based encapsulation systems to enhance interfacial adhesion to substrates and thermal stability; applied via spin-coating or inkjet printing, followed by thermal curing |
| High-Performance Polymers | Monomer for high-temperature-resistant polyimide resins | Copolymerized with pyromellitic dianhydride (PMDA) or biphenyl tetracarboxylic dianhydride (BPDA) in polar aprotic solvents (e.g., NMP), followed by chemical or thermal imidization to produce films or molding compounds |
Manufacturing Quality Control of 1,3-Bis(2,4-diaminophenoxy)propane tetrahydrochloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by retention time and UV absorbance relative to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone) by gas chromatographic separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion using atomic emission spectroscopy. |
| Chloride Ion Content | Ion Chromatography | Separates and quantifies chloride ions based on anion exchange and conductivity detection. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode. |
| Loss on Drying | Gravimetric Thermogravimetry | Determines volatile content by mass loss after drying at 105 C for 2 hours under controlled conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using capillary tube and calibrated thermometer. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder using standardized cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder by measuring angular scattering pattern of laser beam. |
