Manufacturing Quality Control of 1,1,2-Trimethyl-1H-benz[e]indole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities based on retention time and UV spectral match; quantified relative to main peak. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate) per ICH Q3C. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine-based reagent to determine trace water content in the sample. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, with detection at sub-ppt levels. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by weighing of residual inorganic ash after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus per USP <741>. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using sodium D-line light source to assess chiral purity and identity. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue after ignition at 600 C; indicates inorganic contaminants or catalyst residues. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size via light scattering pattern generated by dispersed particles in air stream. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated electrode to assess acidic/basic impurities. |
