Manufacturing Quality Control of 2,4-DICHLORO-7H-PYRROLO2,3-DPYRIMIDINE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with methanol/water or acetonitrile/buffered salt as mobile phase. The UV detector (e.g., 254 nm) quantifies the main peak area to calculate purity. Suitable for assay of active pharmaceutical ingredients and impurity analysis. |
| Related Substances (Impurities) | HPLC (Gradient Elution) | Employs a gradient elution program to separate the main component from potential process impurities and degradation products. Impurity levels are evaluated based on relative retention times and peak areas, in compliance with ICH Q3A/B guidelines. |
| Water Content | Karl Fischer Titration | Determines water content using volumetric or coulometric methods to ensure compliance with limits for loss on drying or moisture content (typically <0.5%). |
| Residual Solvents | Gas Chromatography (GC) with Headspace Injection | According to ICH Q3C guidelines, residual organic solvents (e.g., methanol, ethanol, DMF) are quantified using capillary column and FID detection with headspace sampling. |
| Loss on Drying | Oven Drying Method | Sample is dried at a specified temperature (e.g., 105°C) to constant weight. The percentage weight loss is calculated to assess total content of volatile substances and moisture. |
| Melting Point | Capillary Melting Point Apparatus | Determines the temperature range from initial melting to complete melting. Used as a physical constant for identification and preliminary purity assessment (literature value approximately: 220–225°C). |
| Structural Confirmation | Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS), Infrared Spectroscopy (IR) | NMR (¹H, ¹³C) confirms hydrogen and carbon framework; MS (ESI or EI) verifies molecular weight; IR identifies characteristic functional groups. Used together to confirm chemical structure. |
| Heavy Metal Testing | ICP-MS or Atomic Absorption Spectroscopy (AAS) | Following |
| pH Value (if applicable in solution) | pH Meter | If tested in solution, the pH value is measured to determine whether it falls within the expected range, assessing stability and suitability. |
| Specific Optical Rotation (if chiral center present) | Polarimeter | If the molecule contains a chiral center, specific optical rotation is measured to control optical purity. This item is generally not applicable as the compound lacks chiral centers. |
