Manufacturing Quality Control of 4-Bromoresorcinol
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color, physical state, and presence of impurities by naked eye. 4-Bromo-m-phenylenediamine typically appears as a white to off-white crystalline powder. |
| Melting Point | Capillary Melting Point Determination | Load the sample into a capillary tube and heat it in a melting point apparatus or Thiele tube. Record initial and final melting temperatures. The melting range for pure substance is approximately 108–112 °C. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with mobile phases such as methanol-water or acetonitrile-water. Detect using UV detector (e.g., 254 nm or 280 nm). Quantify the main component using external standard method or area normalization, typically requiring ≥98.0%. |
| Related Substances / Impurities | High-Performance Liquid Chromatography (HPLC) | Similar conditions to content determination, but focused on separation and quantification of potential impurities (such as unreacted raw materials, by-products, degradation products, etc.). Establish appropriate detection and quantitation limits; individual impurity ≤0.5%, total impurities ≤1.0%. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at 105 °C until constant weight, measuring mass loss to assess moisture and volatile content. Typically requires ≤0.5%. |
| Residue on Ignition | High-Temperature Incineration Method | Ignite the sample at high temperature (~700–800 °C), then weigh the residual ash to control inorganic impurities. Typically requires ≤0.1%. |
| Water Content | Karl Fischer Titration | Determine water content using either volumetric or coulometric Karl Fischer titration. Suitable for moisture-sensitive organic compounds. Typically requires ≤0.5%. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, measure levels of heavy metals such as lead, cadmium, mercury, and arsenic. Must comply with pharmacopoeial or industry standards (e.g., ≤10 ppm). |
| pH (Solution) | pH Meter Measurement | Prepare an aqueous solution at a specified concentration (e.g., 1% w/v), then measure pH using a calibrated pH meter. Reflects product purity and possible acidic/basic impurities. |
