Manufacturing Quality Control of 3,4',5-TRIMETHOXY-TRANS-STILBENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 306 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities (e.g., mono/di-methoxy analogs, isomers, degradation products) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., methanol, acetone, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to quantify water based on stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As, Ni) after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in sample solution after dissolution and filtration. |
| Sulfated Ash | Gravimetric Analysis | Residue mass measured after high-temperature incineration of sample with sulfuric acid followed by ashing at 700 C. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary apparatus per USP <741>. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light (589 nm) to assess chiral purity (though compound is achiral, detects chiral contaminants). |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via light scattering pattern to determine D10, D50, D90 values. |
| Organic Volatile Impurities (OVI) | GC-MS | Confirmatory identification and quantification of low-level volatile impurities using gas chromatography coupled with mass spectrometry. |
| Residual Palladium | ICP-MS | Ultra-trace quantification of palladium catalyst residue after microwave digestion, using inductively coupled plasma mass spectrometry. |
