Manufacturing Quality Control of 5-Amino-o-cresol
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reverse-phase C18 chromatographic column, with methanol-water or acetonitrile-buffer solution as the mobile phase, and a UV detector detecting at around 254 nm. Quantification of the main component is performed using external standard or internal standard methods. |
| Purity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | After derivatization of the sample (e.g., silylation), components are separated by GC and identified and semi-quantified by MS to evaluate the purity of the sample. |
| Impurity Detection | High-Performance Liquid Chromatography (HPLC) | Same conditions as content determination, with gradient elution used to separate related impurities (such as oxidation products or unreacted raw materials). Impurity content is calculated based on peak area. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | According to ICH guidelines, residual organic solvents (e.g., methanol, ethanol, acetone) from the production process are detected. Separation is achieved using polar or non-polar capillary columns, with FID detection. |
| Moisture Content | Karl Fischer Titration | The quantitative reaction between iodine and sulfur dioxide in a pyridine/methanol system with water is utilized. Moisture content is determined via coulometric or volumetric methods. |
| Melting Point Determination | Capillary Melting Point Method | A sample is placed in a capillary tube and gradually heated in a melting point apparatus. The initial and final melting temperatures are observed to determine the purity and consistency of the substance. |
| Appearance and Color | Visual Inspection | Under specified lighting conditions, the sample is placed on a white background and examined for color, state, and presence of visible foreign matter. |
| Heavy Metal Residue | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After digestion with nitric acid-hydrogen peroxide, heavy metals such as lead, cadmium, mercury, and arsenic are detected to meet pharmacopoeia or relevant standard limits. |
| Polymorphic Analysis | X-ray Diffraction (XRD) | The crystal structure of solid samples is analyzed to confirm the presence of polymorphic forms, which is used for quality consistency and stability studies. |
| Functional Group Identification | Fourier Transform Infrared Spectroscopy (FTIR) | The sample is pressed with potassium bromide or tested using ATR mode to obtain an infrared absorption spectrum, which is compared with standard spectra to confirm the presence of functional groups such as —OH and —NH₂. |
