Manufacturing Quality Control of 2-Hydroxychalcone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 300-350 nm, comparing peak area against a certified reference standard. |
| Appearance | Visual Inspection | Assessment of physical state and color by observing sample in a white background under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated capillary apparatus per USP <741>. |
| Loss on Drying | Gravimetric (Oven Drying) | Measurement of mass loss after drying at 105 C for 2 hours, indicating volatile impurities or residual solvents. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Mass of non-volatile residue remaining after high-temperature incineration (700-800 C) following sulfuric acid treatment. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Heavy Metals | AAS (Lead, Cadmium, Mercury, Arsenic) | Atomic absorption spectroscopy after acid digestion and matrix-matched calibration for regulated toxic elements. |
| Related Substances | HPLC-DAD | Identification and quantification of structurally similar impurities using diode-array detection and retention time comparison. |
| Water Content | Karl Fischer Titration | Volumetric titration based on iodine-sulfur dioxide reaction specific to water, using pyridine-free reagents. |
| Solvent Residues | GC-FID | Gas chromatographic separation followed by flame ionization detection for common residual solvents (e.g., ethanol, acetone, ethyl acetate). |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Specific Optical Rotation | Polarimetry | Determination of rotation angle of plane-polarized light passing through a solution, indicating chiral purity or absence of racemization. |
