Manufacturing Quality Control of 2-HYDROXY-5-NITROBENZYL BROMIDE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Characteristics | Visual Inspection, Melting Point Determination | Observe the color of the sample (usually light yellow to brown crystals), crystal form, and presence of impurities; determine the melting point range (literature value approximately 105–110°C) to assess purity. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a C18 chromatographic column with methanol/water or acetonitrile/water as the mobile phase, and a UV detector (wavelength 254–280 nm) for quantification. Calculate the main component content using external standard method, which is precise and suitable for impurity control. |
| Impurity Analysis | HPLC-UV / HPLC-MS | Use gradient elution to separate potential impurities (such as unreacted raw materials, de-brominated products, oxidation by-products). Identify the structure via retention time comparison and mass spectrometry, meeting ICH Q3B requirements. |
| Bromine Content | Combustion Ion Chromatography (CIC) or Bomb Combustion + Ion Chromatography | After combustion in an oxygen bomb, absorb the sample into an alkaline solution to convert it into bromide ions. Determine Br⁻ concentration using ion chromatography to verify if the bromine atom content matches the theoretical value (theoretical Br% ≈ 38.5%). |
| Moisture Content | Karl Fischer Titration | Determine trace moisture using coulometric or volumetric methods. Control moisture content within ≤0.5% to avoid hydrolysis or stability issues during storage. |
| Solvent Residues | Gas Chromatography (GC) | Use headspace or direct injection with capillary columns such as DB-624 to detect residual solvents like ethanol, acetone, and ethyl acetate from the production process, complying with ICH Q3C standards. |
| UV-Visible Absorption Spectroscopy | UV-Vis Spectrophotometry | Prepare a solution in ethanol or methanol and measure characteristic absorption peaks in the 200–400 nm range (e.g., λmax ≈ 320–340 nm) for qualitative identification and concentration estimation. |
| Melting Point | Capillary Melting Point Method | Precisely determine the melting range and compare with a reference standard to judge crystalline purity. Deviation in melting point may indicate the presence of impurities. |
| Heavy Metal Detection | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determine the content of heavy metals such as lead, cadmium, mercury, and arsenic after acid digestion to ensure compliance with pharmaceutical or reagent-grade standards (e.g., ≤10 ppm). |
| Chloride/Sulfate Impurities | Colorimetric Method (Chinese Pharmacopoeia Method) | Compare with standard sodium chloride or potassium sulfate solutions to control chloride and sulfate ion impurities, suitable for screening of inorganic impurities. |
