Manufacturing Quality Control of 3,5-Dihydroxyacetophenone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by reversed-phase HPLC with UV detection at ~280 nm, using external standard calibration. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-hydroxy analogs, oxidation by-products) against reference standards. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., acetone, methanol, ethyl acetate) per ICH Q3C. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, As, Hg, Cr) after acid digestion, with detection at sub-pptr levels. |
| Loss on Drying (LOD) | Gravimetric (Thermogravimetric) | Mass loss measured after drying at 105 °C under vacuum or nitrogen, reflecting volatile content and residual moisture. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, indicating crystallinity and purity. |
| Residue on Ignition | Sulfated Ash (Gravimetric) | Measurement of inorganic residue after high-temperature ignition (~750 °C), indicating inorganic impurities. |
| Chloride Impurity | Ion Chromatography (IC) | Quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration with iodine generation to determine trace water content in solid sample. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed powder to determine D10, D50, D90 values per ISO 13320. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light to confirm chiral integrity (though compound is achiral, used for identity/contamination check). |
