Manufacturing Quality Control of 5-Norbornene-2,3-dicarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using UV detection at 210-230 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities using gradient reversed-phase HPLC with UV detection. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., acetone, ethyl acetate). |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion, using plasma excitation and optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on an ion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
| Optical Rotation | [alpha]D Measurement | Determination of specific rotation using a polarimeter at 20 C with sodium D-line (589 nm) light source. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change under controlled heating rate. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Residual Palladium (if catalytically hydrogenated) | ICP-MS | Ultra-trace quantification after microwave-assisted digestion using inductively coupled plasma mass spectrometry. |
