Manufacturing Quality Control of Celliton Fast Pink B
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of inorganic ash content after high-temperature incineration (550–600 °C) and subsequent weighing. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of trace metals by plasma-induced atomic emission spectroscopy following acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column and conductivity detection. |
| Related Substances | HPLC-UV | Identification and quantification of structurally similar impurities (e.g., 1,4-dihydroxyanthraquinone, aminoanthraquinone isomers) relative to main peak. |
| Melting Point | Capillary Melting Point Determination | Thermal transition measurement using calibrated capillary apparatus; indicative of crystallinity and purity. |
| Organic Volatile Impurities | GC-FID | Detection and quantification of residual solvents (e.g., DMF, toluene) via gas chromatography with flame ionization detection. |
| Sulfated Ash | Gravimetric Analysis | Determination of non-volatile inorganic residue after sulfuric acid treatment and high-temperature ignition. |
| Bulk Density | USP <616> Tap Density Method | Measurement of mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution based on angular scattering pattern of laser light passing through dispersed particles. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of surface acidity/basicity by pH electrode measurement of a defined suspension (e.g., 1% w/v in water). |
