Manufacturing Quality Control of 2-Methylthiophenothiazine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Ni after acid digestion, using plasma emission spectroscopy with matrix-matched calibration. |
| Sulfur Content | Combustion IC | Oxidative combustion followed by ion chromatographic detection of sulfate ions, calibrated with sodium sulfate standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference samples. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH ethanol solution using phenolphthalein indicator to quantify free acidic impurities. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after controlled high-temperature ashing (700-800 C) to assess inorganic ash content. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser diffraction to determine D10, D50, D90 values per ISO 13320. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C using sodium D-line (589 nm) to confirm chiral integrity and identity. |
