Manufacturing Quality Control of Glyoxalbis(2-hydroxyanil)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~280 nm, based on peak area comparison against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in a methanol-based solvent system. |
| Residual Solvents (e.g., Methanol, Ethanol) | GC-FID | Separation and quantification of volatile solvents by gas chromatography with flame ionization detection using an appropriate capillary column. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppq sensitivity. |
| Chloride Impurity | Ion Chromatography (IC) | Anion separation on a high-capacity suppressor column with conductivity detection; quantified against chloride calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating of a capillary sample; onset and range determined visually or optically. |
| Organic Volatile Impurities (e.g., Aniline, o-Phenylenediamine) | GC-MS | Identification and quantification of structurally related impurities using gas chromatography coupled to mass spectrometry with library matching. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluation of yellow-brown discoloration by matching against APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of inorganic ash content by high-temperature incineration (750–800 °C) followed by precise weighing of residual residue. |
| Specific Optical Rotation | [α]D | Measurement of chiral rotation using a polarimeter at 589 nm (Na D-line), indicating enantiomeric purity if applicable (though compound is achiral, used for consistency verification). |
