| Pesticides | Manufacture of pesticide intermediates | Employed in sulfuration and amination reactions |
Manufacturing Quality Control of N,N-Diethyl-p-phenylenediamine sulfate
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Purity (Content) | High-Performance Liquid Chromatography (HPLC) | A reverse-phase C18 chromatographic column is used with methanol-water or acetonitrile-phosphate buffer as the mobile phase, and a UV detector (e.g., 254 nm) for detection. It can effectively separate para-amino-diethyl-aniline sulfate and its impurities, providing accurate quantification suitable for content determination. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Suitable for qualitative and quantitative analysis of volatile impurities. The sample needs to undergo derivatization before detection, which allows identification of structural analogs or synthetic byproducts. |
| Related Substances | High-Performance Liquid Chromatography (HPLC, Active Substance Self-Comparison Method) | By setting up reference solution and test solution, the area of the main peak and each impurity peak is compared to evaluate potential degradation products or synthetic byproducts, complying with pharmacopoeia requirements. |
| Content Determination | UV-Visible Spectrophotometry (UV-Vis) | The characteristic absorption at specific wavelengths (e.g., 260–270 nm) is utilized to calculate content via standard curve method. The operation is simple, but it is easily affected by coexisting impurities; baseline correction should be noted. |
| Structure Identification | Nuclear Magnetic Resonance Spectroscopy (NMR, ¹H NMR, ¹³C NMR) | Used to confirm molecular structure, providing information on hydrogen and carbon atom chemical shifts, coupling constants, etc., an important means for confirming compound identity. |
| Thermal Analysis | Differential Scanning Calorimetry (DSC) | By measuring the heat absorbed or released during heating, it determines melting point, crystalline state, and thermal stability of the sample, assisting in judging purity and crystal form. |
| Moisture Content | Karl Fischer Titration | Specifically used to determine trace moisture, suitable for moisture-sensitive samples. The results are accurate and widely applied in quality control of pharmaceuticals and fine chemicals. |
| Ignition Residue | High-Temperature Ashing Method (High-Temperature Crucible Method) | The sample is calcined at high temperature (approximately 500–600 °C) until constant weight is achieved, determining the amount of inorganic residue to reflect metal ions or inorganic salt contamination in the sample. |
