Industrial Applications of CIS-5-NORBORNENE-EXO-2,3-DICARBOXYLIC ANHYDRIDE
| Industry | Application | Process |
|---|---|---|
| Electronic Materials Industry | Electronic encapsulation materials, photoresist resins | Used in ring-opening polymerization or curing reactions with epoxy resins or other resins to produce high-performance electronic encapsulation molding compounds or photoresist base resins, leveraging its low moisture absorption and low dielectric constant. |
| Polymer Chemical Industry | High-temperature-resistant engineering plastics, polyimide resins | Employed as a modifying monomer in ring-opening metathesis polymerization (ROMP) or reaction with diamine monomers to incorporate norbornene structures, thereby enhancing thermal stability and mechanical strength. |
| Composite Materials Industry | Advanced composite matrix resins | Blended with epoxy resins or anhydride curing agents via melt compounding followed by thermal curing to manufacture composites exhibiting superior weather resistance and mechanical performance. |
| Adhesives Industry | High-temperature-resistant structural adhesives | Serves as an anhydride curing agent or reactive diluent in the crosslinking cure of epoxy resins, increasing the adhesive’s glass transition temperature (Tg) and bond strength. |
| Pharmaceutical Chemical Industry | Pharmaceutical synthesis intermediates | Utilized as a precursor in ring-opening or derivatization reactions—leveraging the high reactivity of its norbornene backbone and anhydride group—to synthesize drug molecule precursors with targeted biological activity. |
| Coatings Industry | Insulating coatings, high-temperature-resistant powder coatings | Reacted with diols or epoxy resins via esterification or addition reactions to synthesize polyester resins or modified epoxy resins containing rigid cyclic structures, delivering excellent electrical insulation and thermal resistance. |
Manufacturing Quality Control of CIS-5-NORBORNENE-EXO-2,3-DICARBOXYLIC ANHYDRIDE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of visible impurities under natural or standard lighting conditions. It is typically a white to off-white crystalline powder. |
| Melting Point | Capillary Melting Point Method (e.g., Pharmacopoeia Method) | Fill the sample into a melting point capillary tube and place it in a melting point apparatus. Heat at a specified rate and record the temperature range from initial melting to complete melting, used to assess purity and crystalline consistency. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a suitable water-organic solvent mixture (e.g., acetonitrile or methanol) as the mobile phase. Detection is performed using a UV detector (typically 210–230 nm), and the content is calculated using an external standard method or area normalization method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Similar to the assay conditions but with optimized separation gradients to detect and quantify cis-/trans-isomers, hydrolysis products (e.g., acid), synthesis intermediates, and other organic impurities. |
| Water Content | Karl Fischer Titration | Based on the principle of potentiometric titration, the sample is reacted quantitatively with Karl Fischer reagent to determine the moisture content, which is typically controlled to ≤0.5%. |
| Residual Solvents | Gas Chromatography (GC) | Analyze using headspace or direct injection with an FID detector. Residual solvents (e.g., toluene, dichloromethane) from the manufacturing process are tested in accordance with ICH Q3C guidelines. |
| Infrared Spectroscopic Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Prepare a KBr pellet or use an ATR sample, measure the infrared absorption spectrum, and compare with a reference standard to confirm characteristic functional groups (e.g., acid anhydride C=O double peaks at ~1860 cm⁻¹ and 1780 cm⁻¹). |
| pH Value (if dissolved in solution) | pH Meter Method | Dissolve the sample in water or a specified solvent at a defined concentration, and measure the pH using a calibrated pH meter. This indirectly reflects the degree of hydrolysis or level of acidic impurities. |
