Industrial Applications of 94525-05-0
| Industry | Application | Process |
|---|---|---|
| Polymers | Synthesis of high-performance polyimides | Used as a diamine monomer in two-step condensation polymerization with aromatic dianhydrides—first forming polyamic acid, followed by thermal imidization—to produce high-temperature-resistant, high-mechanical-strength polyimide materials |
| Electronics | Insulating layers for flexible electronic devices | Applied as a fluorinated aromatic diamine in solution-based film formation to prepare low-dielectric-constant, thermally stable polyimide films for flexible circuit substrates |
| Aerospace | High-temperature structural composite materials | Employed as a curing component in specialty polyimide resins to fabricate high-temperature-resistant, low-coefficient-of-thermal-expansion composite parts via hot-pressing or compression molding |
| Optoelectronics | Synthesis of fluorinated optoelectronic polymers | Used as a comonomer in condensation or step-growth polymerization to produce fluorinated polyimides with high refractive index and excellent optical transparency for OLED encapsulation or optical waveguides |
Manufacturing Quality Control of 94525-05-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., mono-substituted analogs, hydrolysis products) using gradient HPLC and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., toluene, THF, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As, Cr) after acid digestion by inductively coupled plasma mass spectrometry with isotope dilution. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion at 700 C followed by sulfuric acid treatment and final ignition. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of freely settled and then tapped powder sample per ASTM D1895. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution in dispersed dry or wet state using Mie scattering theory. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity of a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Organic Volatile Impurities (OVI) | GC-MS | Identifies and quantifies unknown or unspecified volatile organic impurities using gas chromatography coupled with mass spectrometry. |
