Manufacturing Quality Control of CI 37155
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~610 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Inorganic Ash | Gravimetric Analysis (Ignition at 550°C) | Residue mass after high-temperature combustion of sample, representing non-volatile inorganic impurities. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification by plasma ionization and mass spectrometric detection with sub-ppt sensitivity. |
| Chloride Impurity | Potentiometric Titration (AgNO₃) | Titration with silver nitrate using silver electrode to detect endpoint via chloride ion complexation. |
| pH of Aqueous Suspension | pH Meter Measurement | Electrochemical measurement of hydrogen ion activity in a standardized 1% w/v aqueous dispersion. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution (D10, D50, D90). |
| Color Strength (Tinting Strength) | Reflectance Spectrophotometry | Comparison of Kubelka-Munk transformed reflectance values against a primary standard under D65 illumination. |
| Organic Volatile Impurities (e.g., residual solvents) | GC-FID | Separation and quantification of volatile organic residues using capillary column gas chromatography with flame ionization detection. |
| Thermal Stability (Onset Decomposition Temperature) | TGA | Measurement of mass loss versus temperature under controlled nitrogen atmosphere to determine decomposition onset (e.g., Tonset at 1% weight loss). |
