| Industry | Application | Process |
|---|---|---|
| Agrochemicals | Intermediate for the synthesis of the insecticide quinalphos | Reaction with O,O-diethyl thiophosphoryl chloride |
| Agrochemicals | Intermediate for the synthesis of the fungicide mepronil | Used as a starting material in organic synthesis |
| Pharmaceuticals | Intermediate for the synthesis of pharmaceutical compounds | Serves as a key structural unit for chemical modification |
| Organic Synthesis | Preparation of other quinoxaline derivatives | Acts as a nucleophile or coupling precursor |
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity/Content Determination | High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column with a mobile phase of methanol-water or acetonitrile-water, detected by UV detector (typically at 254 nm or 280 nm). The main component content of 2,6-dichloroquinoxaline is calculated using external standard method or area normalization, to assess its purity. |
| Related Substances (Impurities) Testing | High-Performance Liquid Chromatography (HPLC) | Similar conditions to content determination, but gradient elution program is optimized to achieve good separation between the main peak and potential impurities (e.g., monochlorinated derivatives, oxidation products, synthetic intermediates). Quality control is performed by setting impurity limits (e.g., individual impurity ≤ 0.5%, total impurities ≤ 1.0%). |
| Melting Point Determination | Capillary Melting Point Method | Sample is loaded into a melting point capillary and heated in a melting point apparatus at a specified rate (e.g., 1–2°C/min). The temperature range from initial to final melting is recorded. The typical melting point of 2,6-dichloroquinoxaline is approximately 170–173°C, used for preliminary assessment of purity and crystalline consistency. |
| Drying Loss | Drying Weight Loss Method (Thermogravimetric Analysis optional) | Dried at 105°C to constant weight; the percentage of mass loss is measured to control moisture and volatile impurities. Generally requires drying loss ≤ 0.5%. |
| Residual Ash / Sulfated Ash | Ignition Residue Test Method | Sample is ignited at high temperature (approximately 700–800°C), and the residual inorganic matter is weighed. Used to control inorganic salts or metal catalyst residues. Typically requires ignition residue ≤ 0.1%. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace injection or direct injection with a polar capillary column such as DB-624 and FID detection. Quantitative analysis of organic solvents potentially remaining from synthesis (e.g., dichloromethane, toluene, DMF), complying with ICH Q3C guideline limits. |
| Elemental Impurities (e.g., Cl, Heavy Metals) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Trace-level detection of possible heavy metal impurities (e.g., Pd, Cu from catalysts); chlorine content may be verified via ion chromatography or oxygen flask combustion titration to confirm consistency with theoretical chlorine content. |
| Structure Confirmation | Proton Nuclear Magnetic Resonance (¹H NMR), Mass Spectrometry (MS), Infrared Spectroscopy (IR) | Used for structural confirmation of active pharmaceutical ingredients or key intermediates: ¹H NMR verifies aromatic proton signal positions and integration ratios; MS confirms molecular ion peaks (m/z = 184/186/188, consistent with Cl isotopic distribution); IR identifies characteristic functional group absorption bands. |
