Manufacturing Quality Control of 2,5-Dichlorobenzene-1,4-diamine
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and visible impurities under natural light or standard illumination. Typically appears as a white to pale yellow crystalline powder. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase C18 column with UV detection (e.g., 254 nm). Compare the peak area of the main component with that of a reference standard to calculate purity. Suitable for quantitative analysis of the target compound and related substances. |
| Content Determination | HPLC External Standard Method or Titration | HPLC Method: Construct a standard curve using reference standards of known concentration to determine the content of the main component in the sample; Titration Method: Non-aqueous titration (e.g., perchloric acid titration) can be used to determine amino group content, indirectly reflecting the effective ingredient level. |
| Related Substances (Impurities) | HPLC Method (Gradient Elution) | Optimize the mobile phase to achieve separation between the main component and impurities (such as oxidation products, unreacted raw materials, isomers, etc.). Detect and control individual impurity peaks within specified limits. Typically, individual impurities ≤ 0.5%, total impurities ≤ 1.0%. |
| Moisture | Karl Fischer Titration | Quantitatively determines water content based on the reaction between iodine and sulfur dioxide in the presence of pyridine and methanol. Suitable for precise measurement of trace moisture (generally required ≤ 0.5%). |
| Melting Point | Capillary Melting Point Method | Determine the initial and complete melting temperatures using a melting point apparatus. The melting range for this substance is typically 145–150°C, serving as a preliminary assessment of purity and consistency. |
| Residual Solvents | Gas Chromatography (GC) | Follow ICH guidelines to detect organic solvents potentially residual from production processes (e.g., methanol, ethanol, dichloromethane). Quantitative analysis performed using appropriate chromatographic columns and FID detectors. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, measure levels of heavy metals such as lead, cadmium, mercury, and arsenic. Total heavy metals generally required to be ≤ 20 ppm. |
| Loss on Ignition (Sulfate Ash) | Gravimetric Method | After high-temperature ignition and treatment with sulfuric acid, weigh the residual inorganic matter to assess inorganic impurity levels. Typically required to be ≤ 0.1%. |
