Manufacturing Quality Control of 9-METHYLANTHRACENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 9-methylanthracene by separation on a reversed-phase column and UV detection at ~254 nm, comparing peak area to a certified reference standard. |
| Appearance | Visual Inspection | Assessment of physical state and color against a white background under controlled lighting; acceptable material is off-white to pale yellow crystalline solid. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus; conforms to literature value (110–112 °C). |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines inorganic ash content by high-temperature combustion (700–800 °C) and weighing residual inorganic matter. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures volatile content (e.g., solvents, moisture) by weight loss after drying at 105 °C under vacuum or nitrogen. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As, Cr) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chlorinated Impurities (e.g., chlorobenzenes) | GC-ECD | Detects trace chlorinated organic impurities via gas chromatography with electron-capture detection, leveraging high sensitivity for Cl-containing compounds. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines trace water by electrochemical iodine generation and stoichiometric reaction with water in anhydrous methanol-based electrolyte. |
| Related Substances (Impurity Profile) | HPLC-DAD | Identifies and quantifies structurally related impurities (e.g., anthracene, 9-bromoanthracene, 9-anthraldehyde) using diode-array detection and retention time matching. |
| Sulfated Ash | Gravimetric Analysis | Measures residue after incineration with sulfuric acid treatment, indicating inorganic sulfate-forming contaminants. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm absence of chiral contamination (though 9-methylanthracene is achiral, used to detect optically active impurities). |
