Manufacturing Quality Control of 2,5-Dichlorobenzo-1,4-quinone
| 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. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in a methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to combust organic matter; residue weight reflects inorganic impurities. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other heavy metals after acid digestion, based on atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities (e.g., mono-chloro or tri-chloro quinones) using diode-array detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change; correlates with crystallinity and purity. |
| Organic Volatile Impurities | GC-FID | Detection and quantification of residual solvents (e.g., acetone, dichloromethane) using flame ionization detection. |
| Sulfated Ash | Gravimetric Analysis | Sample treated with sulfuric acid and ignited at 600-700 C; ash weight indicates total inorganic sulfate-forming residues. |
| Appearance | Visual Inspection | Assessment of physical form, color, and homogeneity against established reference standards under controlled lighting. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine size distribution of dry powder particles. |
| Bulk Density | Tap Density Measurement | Mass per unit volume measured after standardized tapping of a known mass in a graduated cylinder. |
