Manufacturing Quality Control of 1,1-Di-p-tolyl-2-propyn-1-ol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals by plasma excitation and elemental emission spectroscopy at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard specifications under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral centers in solution at specified concentration and path length. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling organic impurities by analyzing vapor phase above sample at controlled temperature. |
| Residual Solvents | Gas Chromatography (GC) with FID or MS detection | Identifies and quantifies process solvents based on retention times and calibration curves. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular scattering pattern of laser beam. |
