| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Determination | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with acetonitrile-water or methanol-buffer salt as the mobile phase. The main component peak area is quantified using a UV detector (e.g., 254 nm or 280 nm) to calculate purity. Suitable for accurate and rapid analysis of organic compound purity. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Analyzes chemical shifts, coupling constants, and other parameters of hydrogen and carbon atoms in the molecule via ¹H NMR and ¹³C NMR to confirm whether the structure of the target compound matches that of 6-chloro-3-formylchromone. |
| Impurity Analysis | HPLC-UV or HPLC-MS | Employs high-resolution liquid chromatography coupled with UV or mass spectrometry detectors to separate and identify process impurities, degradation products, etc. Can establish an impurity profile for qualitative and semi-quantitative analysis. |
| Assay (Content Determination) | HPLC External Standard Method / Internal Standard Method | Calculates the content of 6-chloro-3-formylchromone in the sample by comparing peak areas with those of known concentration reference standards. The internal standard method improves reproducibility and is suitable for complex matrix samples. |
| Water Content | Karl Fischer Titration | Utilizes electrochemical titration to precisely measure trace moisture content in the sample, avoiding adverse effects of water on product stability or reactivity. |
| Residual Solvent Testing | Gas Chromatography (GC-FID or GC-MS) | Headspace or direct injection is used; residual organic solvents (e.g., methanol, ethyl acetate, DMF) are separated using a capillary column and quantified by FID or MS detectors, in compliance with ICH Q3C guidelines. |
| Melting Point | Capillary Melting Point Apparatus | Determines the temperature range at which the compound transitions from solid to liquid. Used as a physical constant for preliminary assessment of substance purity and consistency. |
| Loss on Drying | Oven Drying Method | Samples are dried to constant weight at a specified temperature (e.g., 105°C), and the percentage weight loss is calculated to evaluate levels of volatile substances or adsorbed water. |
| Heavy Metal Testing | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | After sample digestion, measures residual levels of elements such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeial or regulatory limits for heavy metals (e.g., <10–20 ppm). |
| Specific Optical Rotation (if applicable) | Polarimeter | If the molecule contains chiral centers or exhibits optical activity, optical rotation is measured to control stereochemical consistency. However, 6-chloro-3-formylchromone is typically non-chiral, so this test may not be applicable. |
