Manufacturing Quality Control of 4-HYDROXYCHALCONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 350 nm. |
| Related Substances | HPLC-DAD | Separation and identification of impurities by retention time and UV spectral matching; quantification relative to main peak using external standard or area normalization. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate) based on calibrated response factors. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic mass spectrometry for high sensitivity and specificity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration with iodine-based reagent to determine total water content via stoichiometric reaction with water. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using controlled heating and visual observation of solid-to-liquid phase change. |
| Loss on Drying | Gravimetric Method | Mass loss measured after drying under specified temperature and vacuum conditions to determine volatile and moisture content. |
| Residue on Ignition | Sulfated Ash Method | Weight of inorganic residue remaining after high-temperature combustion in presence of sulfuric acid, indicating inorganic impurities. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Turbidimetric Method | Formation of barium sulfate precipitate in acidic medium; quantification via light scattering measurement at 420 nm. |
| Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution, indicating enantiomeric composition. |
| pH of Aqueous Suspension | pH Meter | Electrochemical measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
