Manufacturing Quality Control of 3-(4-Hydroxyphenyl)propionic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification against reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents based on retention time and peak area calibration. |
| Heavy Metals | ICP-OES | Multi-element determination of Pb, Cd, Hg, As, and others 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. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by sulfuric acid treatment and final weighing of residual inorganic 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 analysis using capillary tube method; temperature at which solid-to-liquid phase transition occurs is recorded. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity under controlled white light against established visual standards. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to calculate particle size distribution in dry or dispersed state. |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured after heating sample at 105 C for 2 hours; reflects volatile content including residual moisture and solvents. |
