Manufacturing Quality Control of 4,6-DICHLORORESORCINOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 275 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., mono-chloro isomers, dichloro by-products) via gradient HPLC-UV against qualified impurity standards. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C in a platinum crucible, then weighing the non-volatile residue after cooling. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy measuring absorbance of characteristic wavelengths after acid digestion and matrix matching. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential inflection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP <741>. |
| Organic Volatile Impurities | GC-FID | Gas chromatography with flame ionization detection to identify and quantify residual solvents (e.g., acetone, methanol, toluene). |
| Sulfated Ash | Gravimetric Analysis | Ignition after sulfuric acid treatment to convert metals to sulfates, followed by weighing of residue. |
| pH of Aqueous Suspension | pH Meter Measurement | Measurement of pH in a 1% w/v suspension in distilled water using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate volume-based particle size distribution in dispersed slurry. |
| Bulk Density | Graduated Cylinder Method | Mass of sample freely poured into a standardized cylinder divided by its settled volume (ASTM D1895). |
