| Agrochemicals | Agrochemical intermediates | Used in the synthesis of herbicides, among others |
| Fine chemicals | Polymerization inhibitors and dye intermediates | Produced via condensation and substitution reactions |
Manufacturing Quality Control of 4-PHENOXYBENZOIC ACID
| Test Item | Common Analytical Methods | Method Overview |
|---|---|---|
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Uses a C18 reversed-phase column with methanol/water or acetonitrile/water as mobile phase. Detection is performed using a UV detector (254 nm). The content of the main component is quantified by external or internal standard method, and impurity peaks can be simultaneously evaluated. |
| Impurity Profile Analysis | High-Performance Liquid Chromatography (HPLC) or LC-MS | HPLC with gradient elution is used to separate possible synthetic intermediates (e.g., phenol, 4-chlorobenzoic acid) and oxidative degradation products. LC-MS provides structural identification by offering molecular weight information to confirm the origin of impurities. |
| Melting Point | Melting Point Apparatus (Capillary Method) | According to pharmacopoeia methods, the sample is packed into a capillary tube and heated gradually. The temperature range from the onset of melting to complete melting is recorded. The typical melting point range is approximately 138–142°C, used for preliminary identification and purity assessment. |
| Moisture Content | Karl Fischer Titration | Quantitatively determines trace moisture in the sample based on the reaction of iodine, sulfur dioxide, pyridine, and methanol. It is suitable for accurate moisture determination in solid organic acids to ensure compliance with drying standards. |
| Chlorides/Inorganic Impurities | Ion Chromatography (IC) or Colorimetry | Ion chromatography is used to detect residual inorganic anions such as chloride ions in the sample; alternatively, the silver nitrate colorimetric method is used to determine whether chloride content is below specified limits (e.g., ≤0.1%). |
| Heavy Metal Residues | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After wet digestion of the sample, AAS or inductively coupled plasma mass spectrometry (ICP-MS) is used to determine the content of heavy metals such as lead, cadmium, mercury, and arsenic, ensuring compliance with ICH Q3D or pharmacopoeia limits. |
| UV Absorption Characteristics | UV-Visible Spectrophotometry (UV-Vis) | A solution is prepared in ethanol or methanol, and a scan is performed between 200–400 nm to determine characteristic absorption peaks (typically around 270–280 nm). This method is used for qualitative identification and concentration estimation (requires calibration curve). |
| Crystal Form Analysis (Optional) | X-Ray Powder Diffraction (XRPD) | Used to confirm the crystalline form of the active pharmaceutical ingredient (API), preventing differences in solubility and stability due to different crystal forms. It is applicable for quality control of high-purity APIs. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection with a DB-624 capillary column to detect residual organic solvents that may be present from the manufacturing process (e.g., methanol, ethanol, ethyl acetate), ensuring compliance with ICH Q3C standards. |
