Manufacturing Quality Control of perylene-3,4,9,10-tetracarboxylic acid
| 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 260-350 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities (e.g., mono-, di-, tri-carboxy pyrene derivatives) using gradient elution and UV absorbance. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, NMP, chloroform) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride anions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Residue mass measured after high-temperature incineration (500-600 C) following sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volume-based particle size distribution in dispersed suspension. |
| Bulk Density | USP <616> Tap Density Test | Mass per unit volume determined after mechanical tapping of a powder sample in a calibrated cylinder. |
| Organic Volatile Impurities (OVI) | GC-MS | Identification and quantification of non-aqueous volatile impurities using gas chromatography coupled with mass spectrometric detection. |
| Color (Solution) | Visual Comparison or Colorimeter | Assessment of solution color intensity (in specified solvent and concentration) against standard platinum-cobalt scale or digital color measurement. |
