Manufacturing Quality Control of 5-BROMO-3-METHYLINDOLE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification via reversed-phase HPLC with UV detection at ~280 nm, comparing peak area to a certified reference standard. |
| Related Substances (Impurities) | HPLC-UV/DAD | Separation and identification of structurally related impurities (e.g., regioisomers, bromination by-products) using gradient HPLC with diode-array detection. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., DMF, toluene, methanol) per ICH Q3C guidelines. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification of toxic elements after acid digestion, achieving sub-pptr detection limits per ICH Q3D. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Appearance & Color | Visual Inspection / Hazen Color Scale | Subjective assessment of crystalline homogeneity and quantitative color evaluation against platinum-cobalt standards. |
| Residue on Ignition | Gravimetric Analysis | Mass measurement of non-volatile inorganic residue after high-temperature ashing at 700–800 °C. |
| Chloride Impurity | Ion Chromatography (IC) | Anion-exchange separation and conductivity detection of chloride ions derived from potential chlorinated side products or reagents. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to detect chiral impurities or enantiomeric excess (if applicable; compound is achiral but method verifies absence of chiral contaminants). |
