| Pesticide Industry | Intermediate | Used in the synthesis of specific thiourea-based pesticides or plant growth regulators |
Manufacturing Quality Control of N,N'-Diethylthiourea
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state (e.g., white or off-white crystalline powder), and presence of impurities by visual examination. |
| Melting Point | Capillary Melting Point Method | Pack the sample into a capillary tube and gradually heat it in a melting point apparatus; record the initial and final melting temperatures to assess purity and consistency. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with an appropriate mobile phase (e.g., methanol-water or acetonitrile-water system) for separation, and quantify the main component using a UV detector (typically 210–230 nm). |
| Gas Chromatography (GC) | Suitable for volatile thiourea derivatives; separate components via gas chromatography and quantify using FID or NPD detectors (method applicability must be validated). | |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employ gradient or isocratic elution to separate and detect potential process impurities and degradation products; calculate impurity levels using area normalization or corrected relative response factor methods. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight; calculate the percentage weight loss to evaluate moisture and volatile content. |
| Residue on Ignition | High-Temperature Ashing Method | Char the sample and then ignite at high temperature (typically 700–800°C); weigh the remaining inorganic residue to control levels of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Digest the sample and measure residual levels of heavy metal elements such as lead, arsenic, cadmium, and mercury to ensure compliance with pharmacopoeial or industry standard limits. |
| pH Value (Solution) | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1%), and measure its acidity or alkalinity using a calibrated pH meter to reflect the presence of acidic or basic impurities. |
