Industrial Applications of Pirimiphos-methyl
| Industry | Application | Process |
|---|---|---|
| Agriculture | Insecticide for controlling stored-grain pests (e.g., rice weevil, granary weevil, red flour beetle) and public health pests (e.g., cockroaches, flies) | Fumigation or spray application, commonly used for pest control in enclosed spaces such as warehouses, grain silos, and transport vehicles |
| Public Health | Public health insecticide for controlling pests in indoor and urban environments | Spray or residual spray application to pest resting sites, including walls and cracks |
| Grain Storage | Protection of stored cereals, legumes, dried fruits, and other commodities against insect infestation | Direct application to commodity surfaces or packaging materials; also used for empty-bin disinfection |
Manufacturing Quality Control of Pirimiphos-methyl
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Utilizes a C18 reversed-phase chromatographic column with methanol-water or acetonitrile-water as the mobile phase, detected by a UV detector (220–254 nm). Quantification is performed via external or internal standard methods, suitable for precise determination of methyl pyrimiphos content in pure substances and formulations. |
| Content Determination | Gas Chromatography (GC) | Employs a capillary column (e.g., DB-5 or HP-5) coupled with a flame photometric detector (FPD) or nitrogen-phosphorus detector (NPD), leveraging the phosphorus-containing nature of the compound for high-sensitivity detection. Suitable for samples with good volatility; derivatization may be required to enhance stability. |
| Impurity Analysis | High-Performance Liquid Chromatography-Tandem Mass Spectrometry (HPLC-MS/MS) | Separation via HPLC followed by qualitative and quantitative analysis using tandem mass spectrometry. Capable of detecting degradation products, synthetic intermediates, and trace impurities (e.g., pyrimiphos, chlorinated derivatives), offering high sensitivity and selectivity. |
| Residue Detection (Agricultural Products/Environment) | Gas Chromatography-Mass Spectrometry (GC-MS) | After sample extraction (e.g., acetonitrile) and purification (QuEChERS method), separation is performed by GC, and detection is carried out in MS/MS multiple reaction monitoring (MRM) mode. This is a legally recognized method for detecting trace residues of methyl pyrimiphos in food, soil, and water. |
| Hydrolysis Stability Testing | HPLC with Timed Sampling | Samples are placed in buffer solutions of varying pH and maintained at constant temperature. Aliquots are taken at timed intervals and analyzed by HPLC to determine residual concentration, enabling calculation of half-life and assessment of hydrolysis behavior in environmental or formulation contexts. |
| Melting Point Determination | Melting Point Apparatus | Uses a digital melting point apparatus to measure the melting point range of pure methyl pyrimiphos (literature value: approximately 58–62°C), used to assess raw material purity and crystalline form consistency. |
| Water Content Determination | Karl Fischer Titration | Utilizes coulometric or volumetric methods to determine trace water content in samples, ensuring raw materials meet formulation process requirements for moisture content (typically ≤0.5%). |
| Chloride Ion/Inorganic Impurity Detection | Ion Chromatography (IC) | Applicable for detecting inorganic impurities such as chloride ions and phosphate salts potentially introduced during production. Separation is achieved via an anion-exchange column with conductivity detection, ensuring product purity. |
| Particle Size Distribution (Formulations) | Laser Diffraction Particle Size Analysis | Used for emulsifiable concentrates, wettable powders, and other formulations to determine the particle size distribution of the active ingredient, ensuring uniform dispersion and consistent efficacy. |
