Manufacturing Quality Control of 1,2,3-Benzenetricarboxylic acid hydrate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies total acidic groups via standardized NaOH titration using phenolphthalein endpoint detection. |
| Water Content | Karl Fischer Titration | Measures water by electrochemical reaction between iodine, sulfur dioxide, and water in anhydrous methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual mass. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Hg) via atomic emission spectroscopy after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under controlled pH and temperature, then measures precipitate mass. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection at 254 nm. |
| Loss on Drying | Thermogravimetric Analysis | Measures volatile loss (including hydrate water) by weight change upon controlled heating to 105 C. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in laser light scattering from dispersed particles. |
| Melting Point | Capillary Melting Point Apparatus | Identifies melting onset and range via visual observation of solid-to-liquid transition in capillary tube. |
| Organic Volatile Impurities | GC-FID | Detects and quantifies residual solvents using gas chromatography with flame ionization detection. |
