Manufacturing Quality Control of 4-Fluoroindole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 280 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., 4-chloroindole, indole, fluorobenzene derivatives) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., toluene, THF, methanol) based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to determine water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, based on element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of sample against established reference standards under controlled lighting. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator; calculated as mg KOH per g sample. |
| Loss on Drying | Gravimetric Analysis | Measurement of mass loss after drying under specified temperature and vacuum conditions to determine volatile and moisture content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral impurities or enantiomeric excess, using sodium D-line source. |
| Residue on Ignition | Sulfated Ash Test | Determination of non-volatile inorganic residue after high-temperature incineration and sulfuric acid treatment, expressed as percentage weight. |
