| Industry | Application | Process |
|---|---|---|
| Polymers | Functional monomer for synthesizing high-performance polymers | Integrated into polymer backbones via free-radical or ring-opening polymerization to enhance thermal stability and mechanical properties through incorporation of a rigid norbornene structure |
| Photoresists | Enhances resolution and etch resistance in photosensitive resin formulations | Undergoes photo-induced crosslinking upon UV irradiation to form patterned structures with high etch resistance |
| Medical Materials | Synthesized into biodegradable scaffolds or drug delivery carriers | Controlled polymerization yields copolymers with tailored degradation rates for tissue engineering and targeted drug delivery |
| Electronic Materials | Precursor for insulating or dielectric layers | Thermally or photo-initiated crosslinking produces thin-film materials with low dielectric constant and high thermal stability |
| Coatings & Adhesives | Formulated into high-performance coatings and structural adhesives | Enables rapid crosslinking via multifunctional reactivity, improving adhesion and chemical resistance |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid content by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against specified reference under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using capillary tube and calibrated thermometer. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion by atomic emission spectroscopy. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by determining rotation angle of plane-polarized light in solution at specified concentration and path length. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension by measuring angular variation in laser light scattering. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined aqueous slurry using calibrated glass electrode pH meter. |
