Manufacturing Quality Control of 5-Hydroxy-2-methylindole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 280 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities by retention time and UV response relative to main peak. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other heavy metals after acid digestion by measuring elemental emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature combustion in presence of sulfuric acid, followed by weighing of ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting against standard references. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral molecules in solution to confirm identity and enantiomeric integrity. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after ignition at 700-800 C, expressed as percentage of sample weight. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
