Manufacturing Quality Control of trans-1,2-Cyclohexanedicarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies total acid content by neutralization with standardized sodium hydroxide solution using phenolphthalein or potentiometric endpoint detection. |
| Water Content | Karl Fischer Titration | Measures trace water via iodine-sulfur dioxide redox reaction in a methanol-based reagent, with coulometric or volumetric detection. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by high-temperature ashing followed by weighing of residual residue. |
| Heavy Metals | ICP-OES | Quantifies metallic impurities (e.g., Pb, Cd, Fe, Cu) by plasma excitation and elemental emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Related Substances | HPLC with UV Detection | Separates and detects structurally related impurities (e.g., cis-isomer, mono-acid, decarboxylation products) using reversed-phase chromatography and UV absorbance. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm identity and detect chiral impurities (though trans-1,2-CHDA is meso and optically inactive). |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against standard reference under controlled lighting. |
| Solubility in Water | Qualitative Solubility Test | Evaluates dissolution behavior in distilled water at specified temperature and concentration to detect unexpected polarity shifts. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures volatile content (e.g., residual solvents, moisture) by weight loss after controlled heating under nitrogen or air. |
| Iron Content | AAS (Flame Atomic Absorption Spectroscopy) | Quantifies iron impurity by atomization in flame and measurement of characteristic atomic absorption at 248.3 nm. |
