Manufacturing Quality Control of (S)-(+)-6,6'-DIBROMO-1,1'-BI-2-NAPHTHOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 280 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., mono-brominated isomers, unreacted naphthol) using gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., toluene, DMF, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generated electrochemically in a methanol-based reagent. |
| Heavy Metals | ICP-OES | Measures total content of regulated metals (Pb, Cd, Hg, As, Cr) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Loss on Drying | Gravimetric Analysis | Measures volatile matter loss by weight difference before and after drying at 105 C for 2 hours under vacuum. |
| Residue on Ignition | Sulfated Ash Test | Quantifies non-volatile inorganic residue after controlled ignition at 700–750 C following sulfuric acid treatment. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using Mie scattering theory with helium-neon laser illumination. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder using standardized cylinder and funnel apparatus. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness/browning intensity by matching sample solution color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
