Manufacturing Quality Control of 4-Methyl-7H-pyrrolo[2,3-d]pyrimidine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and presence of visible foreign matter under natural light or standard light sources. |
| Infrared Spectroscopy (FT-IR) | Compare the sample with standard spectra by analyzing characteristic absorption peaks to confirm functional groups in the molecular structure and verify the authenticity of the compound. | |
| Nuclear Magnetic Resonance Spectroscopy (1H-NMR, 13C-NMR) | Analyze chemical shifts, coupling constants, and integral areas of hydrogen and carbon spectra to confirm the molecular structure matches the target compound. | |
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase column (e.g., C18) with a UV detector. Quantify the main component content via retention time and peak area, assessing purity. |
| UV-Visible Spectrophotometry (UV-Vis) | Measure concentration using the compound's absorbance characteristics at specific wavelengths, combined with standard curve methods, suitable for rapid content analysis. | |
| Moisture | Karl Fischer Titration | Determine moisture content precisely based on the quantitative reaction between iodine and sulfur dioxide in the presence of water, suitable for trace moisture detection. |
| Residual Solvents | Gas Chromatography (GC) | Detect residual organic solvents (e.g., methanol, ethanol, dichloromethane) from the production process using headspace or solution injection. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak from impurity peaks via gradient elution, calculate the area percentage of each impurity peak, and assess the types and limits of organic impurities in the sample. |
| Melting Point | Capillary Melting Point Determination | Place the sample in a capillary tube and slowly heat it on a heating block, recording the initial and final melting temperatures for preliminary identification and purity assessment. |
| Residue on Ignition | Gravimetric Method | Weigh the mass of the residue after high-temperature combustion of the sample to calculate the content of non-volatile inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Dissolve the sample and measure the content of heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmaceutical or industrial safety standards. |
| Crystalline Form Analysis | X-ray Powder Diffraction (XRPD) | Analyze the crystal diffraction pattern to identify polymorphic phenomena, ensuring product crystalline form consistency, which affects solubility and stability. |
| Particle Size Distribution | Laser Particle Size Analysis | Determine particle size distribution using the principle of laser scattering, suitable for controlling the physical properties of solid APIs. |
