Manufacturing Quality Control of 2-Chloroanthraquinone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., anthraquinone, 1-chloroanthraquinone) using gradient HPLC-UV. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on the reaction of water with iodine and sulfur dioxide in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after incineration at 700-800 C in a muffle furnace. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy following acid digestion and matrix-matched calibration for lead and other regulated metals. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anion using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection to quantify residual solvents (e.g., toluene, chlorobenzene). |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering principles to determine D10, D50, D90 values. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume measured by gently pouring material into a calibrated cylinder and recording settled volume. |
| Color (APHA) | Visual Comparison or Spectrophotometric | Comparison of solution color (in specified solvent) against APHA platinum-cobalt standards or spectrophotometric measurement at 430 nm. |
| Sulfated Ash | Gravimetric Analysis | Weight of residue after combustion with sulfuric acid treatment and subsequent incineration at 700 C. |
