Manufacturing Quality Control of DIPHENYLCYCLOPROPENONE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm the presence of characteristic functional groups in diphenylcyclopropenone (such as C=O, C=C, and cyclopropene structure). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze the chemical shifts, integration area, and coupling constants of hydrogen atoms using nuclear magnetic resonance to verify structural features such as aromatic protons and protons on the cyclopropene ring. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 chromatographic column with methanol-water or acetonitrile-water as the mobile phase, and a UV detector (usually at around 254 nm) for detection. Quantify the main component using external or internal standard methods. |
| Related Substances (Impurity) Check | High-Performance Liquid Chromatography (HPLC) | Similar to the conditions used for content determination, but optimized for separation to detect and quantify potential synthetic by-products or degradation products. Typically set limits for total impurities and individual impurities. |
| Dry Loss | Thermogravimetric Analysis (TGA) or Constant Pressure Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, and determine the percentage of mass loss due to water or other volatile components. |
| Melting Point Determination | Capillary Melting Point Method | Load the sample into a capillary tube and slowly heat it in a melting point apparatus. Observe and record the initial and final melting temperatures to assess purity (pure substances have a narrow melting range). |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection with an FID detector to detect residual organic solvents from the synthesis process (e.g., dichloromethane, toluene), according to pharmacopoeia or ICH guidelines. |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Thiocarbamide Method After Incineration | ICP-MS can sensitively determine multiple metal elements; the traditional method involves incinerating the sample and then colorimetrically determining the total heavy metal limit. |
