| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of antiviral drugs | Used as an intermediate in cyclization and substitution reactions |
| Agrochemicals | Preparation of insecticides or fungicides | Applied to introduce pyridine ring structures |
| Chemical Research | Laboratory reagent | Serves as a precursor for synthesizing heterocyclic compounds |
| Materials Science | Synthesis of functional molecules | Involved in polymerization or modification reactions |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and identification of impurities (e.g., unreacted 2-chloropyridine, hydrolysis products) via retention time matching and/or mass spectral confirmation. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, dichloromethane, toluene) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, achieving sub-ppb sensitivity. |
| Chloride Content | Potentiometric Titration with AgNO₃ | Direct titration using silver nitrate; endpoint detected by silver-selective electrode based on formation of AgCl precipitate. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemical generation of iodine to react stoichiometrically with water; precise measurement down to 10 ppm. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid–liquid phase transition temperature using calibrated capillary apparatus per USP <741>. |
| Appearance & Color | Visual Inspection / Hazen Color Scale | Subjective assessment of crystalline form and color intensity compared to platinum-cobalt standards. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue after high-temperature ashing at 700–800 °C. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light to confirm absence of chiral contamination (though compound is achiral, used for identity verification). |
