Manufacturing Quality Control of Ethyl 3-hydroxybenzoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., ethanol, ethyl acetate) against calibrated standards. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma emission spectroscopy. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C after sulfuric acid treatment; residue weighed as inorganic sulfate ash. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent; water reacts stoichiometrically to determine moisture content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the solid-to-liquid phase change under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of crystalline form, color, and absence of visible particulates or discoloration against established reference standards. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using a calibrated glass electrode system. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution; indicates chiral purity and identity. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. angle to determine volume-based particle size distribution in a dispersed slurry. |
