Manufacturing Quality Control of 1,6-Dibromo-2-naphthol
| 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 254 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities based on retention time and UV spectral matching; quantification using external standard or area normalization. |
| Residual Solvents | GC-FID | Gas chromatographic separation followed by flame ionization detection, calibrated with standard solvent mixtures per ICH Q3C guidelines. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; quantified against chloride standard. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particulates or foreign matter against established reference standards. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities (e.g., residual HBr) with standardized NaOH solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue remaining after high-temperature ashing at 700-800 C. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate size distribution based on Mie theory. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral components in solution at specified concentration and path length. |
