Manufacturing Quality Control of 1-Amino-2-bromonaphthalene
| 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 (e.g., 1-naphthylamine, 2-bromonaphthalene) using gradient HPLC-UV with system suitability criteria. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to combust organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, Cr by plasma excitation and emission spectroscopy following acid digestion. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions after aqueous extraction and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated digital apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
| Solubility in Ethanol | Qualitative Solubility Test | Evaluation of complete dissolution in specified volume of ethanol at 20 C with gentle agitation and visual clarity check. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator to quantify acidic impurities (e.g., brominated phenols). |
| Volatile Impurities | GC-FID | Separation and flame ionization detection of low-boiling impurities (e.g., solvents, halogenated benzenes) using capillary column. |
| Bulk Density | Graduated Cylinder Method | Measurement of mass per unit volume for free-flowing powder using standardized tapping procedure per ASTM D1895. |
