Manufacturing Quality Control of 1-Chloro anthraquinone
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state (e.g., powder, crystals), and presence of impurities with the naked eye to determine compliance with specified standards. |
| Melting Point | Capillary Melting Point Determination | Load the sample into a capillary tube and heat it in a melting point apparatus or Thiele tube; record the initial and final melting temperatures to assess purity. |
| Assay (Content Determination) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase of methanol-water or acetonitrile-water; detect with a UV detector (e.g., at 254 nm) and quantify using the external standard method. |
| Drying Loss | Drying Weight Loss Method | Dry the sample to constant weight at a specified temperature (e.g., 105°C) and calculate the percentage weight loss to evaluate moisture and volatile substance content. |
| Residue on Ignition | High-Temperature Ignition Method | Carbonize the sample, then ignite it in a muffle furnace at high temperature (typically 700–800°C); weigh the residual ash to determine inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Thioacetamide Colorimetric Method |
AAS: Measure specific heavy metals (e.g., lead, cadmium, mercury) via atomic absorption; Colorimetric method: React with thioacetamide under acidic conditions to form a colored precipitate, then quantify by colorimetry. |
| Organic Impurities | Thin-Layer Chromatography (TLC) or High-Performance Liquid Chromatography (HPLC) |
TLC: Separate components on a silica gel plate, develop with a suitable solvent, visualize spots, and assess number and Rf values; HPLC: Use gradient elution to separate components and detect impurity peak areas. |
| Chlorine Content | Oxygen Flask Combustion–Potentiometric Titration or Ion Chromatography (IC) |
Oxygen flask combustion converts organic chlorine to chloride ions, followed by potentiometric titration with standard silver nitrate solution; IC: Directly measure chloride ion concentration in the sample. |
