Manufacturing Quality Control of 4-Amino-3-chlorophenol hydrochloride
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, condition, and presence of visible impurities under natural light or standard light source. Typically appears as white to off-white crystalline powder. |
| Identification | Infrared Spectroscopy (IR) | Compare the sample spectrum with a reference spectrum, confirming structural consistency by characteristic absorption peaks (e.g., —NH₂, —OH, C—Cl functional groups). |
| High-Performance Liquid Chromatography (HPLC) | Confirm the identity of the main component by comparing retention time with a reference substance. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column (e.g., C18) with a UV detector (usually set at 254 nm or adjusted according to maximum absorption), quantifying the main component using external or internal standard methods. |
| Non-aqueous Titration | Titrate the free amine in a non-aqueous solvent (e.g., glacial acetic acid) using perchloric acid standard solution to calculate the hydrochloride salt content. Suitable for determining the purity of raw materials. | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution to detect impurity peaks before and after the main peak, calculating individual and total impurity content. Method validation is usually required (specificity, sensitivity, etc.). |
| Moisture | Karl Fischer Method | Determine moisture content using coulometric or volumetric methods. Applicable for organic salts containing trace amounts of water. |
| Dried Loss | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, and calculate the loss due to moisture and volatile substances. |
| Residue on Ignition (Ash Content) | Sulfate Ash Method | Weigh the residual inorganic material after high-temperature incineration of the sample, used to evaluate inorganic impurity content. |
| Chloride | Ion Chromatography or Argentometric Method (Silver Nitrate Titration) | Detect chloride ion content in hydrochloride salts, verifying the ratio of hydrochloride or foreign chloride impurities. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determine the content of heavy metals such as lead, cadmium, mercury, and arsenic after sample digestion, meeting pharmacopoeia limits (e.g., ≤20 ppm). |
| pH Value (Solution) | pH Meter Measurement | Determine the acidity or alkalinity by preparing a certain concentration aqueous solution (e.g., 1% w/v) and measuring it with a calibrated pH meter. |
| Particle Size Distribution | Laser Diffraction Method | Used to assess particle size distribution, which affects solubility and formulation performance. |
| Crystal Form | X-ray Powder Diffraction (XRD) | Identify different crystal forms to ensure consistent crystal structure across batches, which impacts stability and bioavailability. |
