Manufacturing Quality Control of 1,5-DIAMINO-4,8-DIHYDROXYANTHRAQUINONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 500-530 nm. |
| Related Substances | HPLC-DAD | Separation and identification of structurally similar impurities using diode array detection for spectral confirmation and relative response factor-based quantitation. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with iodine, sulfur dioxide, and base in methanol. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (700-800 C) followed by precise weighing. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr by plasma excitation and optical emission spectroscopy after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions after aqueous extraction and filtration. |
| Sulfate Impurity | Turbidimetry | Formation and measurement of barium sulfate precipitate in acidic medium using spectrophotometric absorbance at 420 nm. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection gas chromatography with flame ionization detection for residual solvents (e.g., DMF, methanol, toluene). |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution in dispersed suspension. |
| Bulk Density | Tap Density Measurement | Determination of mass per unit volume after standardized mechanical tapping of a powder sample in a calibrated cylinder. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a defined suspension (1% w/v in water) using calibrated glass electrode and pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using controlled heating rate and visual observation of meniscus movement in capillary tube. |
