Manufacturing Quality Control of 4-Bromo-7-azaindole
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, form (e.g., white to off-white crystalline powder), and check for foreign matter or clumping to assess physical characteristics. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column with an appropriate mobile phase (e.g., methanol/water or acetonitrile/buffer salt system) for separation. Quantify the main peak area using a UV detector (e.g., 254 nm) and calculate the purity percentage. |
| Related Substances | HPLC (Gradient Elution) | Extend the run time or use a gradient program based on the purity test to separate and quantify potential impurities (e.g., starting material, by-products, degradation products). Quantify using area normalization or external standard methods. |
| Moisture | Karl Fischer Titration | Measure moisture content by quantitatively reacting the sample with Karl Fischer reagent, using potentiometric titration. Suitable for determining trace moisture in organic compounds. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection with a DB-624 or similar capillary column for separation. Quantify common residual solvents (e.g., methanol, ethyl acetate, DMF) using an FID detector. |
| Melting Point | Capillary Melting Point Determination | Determine the melting range using a digital melting point apparatus. Verify the physical properties against literature values (approximately 180–185°C). |
| Structural Confirmation | Nuclear Magnetic Resonance (NMR) | Analyze the ¹H NMR and ¹³C NMR spectra to determine the chemical shifts and coupling splitting patterns, confirming the molecular framework and the correct position of substituents. |
| Elemental Analysis | Elemental Analyzer (CHN Analysis) | Determine the carbon, hydrogen, and nitrogen content in the sample and compare it with theoretical values (e.g., for C₇H₅BrN₂: C 43.57%, H 2.61%, N 14.51%) to confirm the molecular composition. |
| Heavy Metals | ICP-MS or Atomic Absorption Spectroscopy | After digestion, measure the total content of heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with ICH Q3D limits (typically ≤ 20 ppm). |
| Dry Loss | Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) under vacuum or atmospheric pressure until constant weight is achieved. Calculate the percentage of mass loss to assess the content of volatile substances. |
