Manufacturing Quality Control of CHROMONE-3-CARBOXALDEHYDE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with the standard spectrum to confirm the presence of characteristic functional groups of chromone-3-carboxaldehyde, such as aldehyde group, aromatic ring, and carbonyl group. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze chemical shifts, integration areas, and coupling constants of hydrogen atoms in the molecule using ¹H NMR to verify structural features, especially the aldehyde proton signal (~9–10 ppm) and aromatic proton signals. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase and a UV detector (typically at 254–320 nm wavelength). Quantify chromone-3-carboxaldehyde using external or internal standard methods. |
| Related Substances / Impurity Testing | High-Performance Liquid Chromatography (HPLC) | Perform gradient elution under the same or optimized conditions as the assay to separate and detect potential impurities such as by-products from synthesis, degradation products, or other organic impurities. Impurity levels are calculated using area normalization or a main component self-reference method with correction factors. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, and measure the weight loss to assess the content of moisture and volatile substances. |
| Melting Point Determination | Capillary Melting Point Method | Use a melting point apparatus to determine the temperature range from initial melting to complete melting. Purity is assessed based on melting range (pure compounds have a narrow range; impurities lower the melting point and broaden the range). |
| Residual Solvents | Gas Chromatography (GC) | Employ headspace or direct injection with an FID detector to detect residual organic solvents (e.g., methanol, dichloromethane, DMF) that may remain from synthesis or purification. Limits are controlled according to pharmacopoeial or ICH guidelines. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After appropriate sample digestion, measure the levels of harmful elements such as lead, cadmium, mercury, and arsenic to ensure compliance with safety standards for pharmaceutical or industrial raw materials. |
