Industrial Applications of 3,5-Dichloropyridine
| Industry | Application | Process |
|---|---|---|
| Agrochemicals | Intermediate in the synthesis of chlorantraniliprole | Reacted with 2,3-dimethyl-2-butene to synthesize ethyl 3-bromo-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxylate |
| Agrochemicals | Key intermediate in the synthesis of halauxifen-methyl (Arylex) | Used in the synthesis of derivatives for constructing pyridine ring structures |
| Pharmaceuticals | Used in the synthesis of novel antibacterial agents and pharmaceutical intermediates | Acts as a nucleophile in coupling reactions or for introducing specific functional groups |
| Chemical Manufacturing | Synthesis of other fine chemical products | Serves as an organic synthesis building block for functional group modifications, including chlorination and coupling reactions |
Manufacturing Quality Control of 3,5-Dichloropyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separation and quantification of structurally similar impurities using retention time and relative response factors. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvent residues are vaporized in sealed vials and analyzed by GC with FID detection. |
| Water Content | Karl Fischer Titration (coulometric mode) | Electrochemical titration where iodine reacts stoichiometrically with water; endpoint detected amperometrically. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element quantification based on element-specific atomic emission intensities after plasma atomization/excitation. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column followed by quantitative detection via changes in solution conductivity. |
| Acid-Base Impurities | Acid-Base Potentiometric Titration | Titration with standardized NaOH or HCl to determine total acidic or basic impurity content via pH inflection point. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the solid phase changes to liquid under controlled heating rate. |
| Appearance | Visual Inspection (against white/black background) | Subjective assessment of physical state, color, and presence of visible particulates or discoloration. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Mass difference measured before and after high-temperature ashing to determine inorganic residue content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution (though 3,5-dichloropyridine is achiral, this checks for chiral contaminants). |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate particle size distribution in dispersed solid samples. |
