Manufacturing Quality Control of 2,2'-DIBROMO-1,1'-BINAPHTHYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-brominated naphthalene, dibromo isomers, unreacted naphthalene) relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., chlorobenzene, acetic acid) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol solvent system. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantitative analysis after acid digestion; detection based on characteristic atomic emission spectra of metal ions. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anions using suppressed conductivity detection after aqueous extraction. |
| Ash Content | Gravimetric Analysis | Determination of inorganic residue mass after high-temperature incineration (550-600 C) and cooling in a desiccator. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via visual observation of solid-to-liquid phase change in a calibrated capillary tube under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
| Bulk Density | ASTM D1895 | Measurement of mass per unit volume of freely settled powder using a standardized graduated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered light intensity patterns generated by dispersed particles in air or liquid medium to derive size distribution. |
| Residual Bromine | Redox Titration | Titration with standardized sodium thiosulfate after liberation of elemental bromine via oxidation in acidic medium, using starch indicator. |
