Industrial Applications of 2,4-DICHLORO-3-AMINOPYRIDINE
| Industry | Application | Process |
|---|---|---|
| Pesticides | Intermediate for synthesizing novel pyridine-based insecticides and fungicides | Used as a starting material—3-amino-2,4-dichloropyridine—to introduce functional groups via nucleophilic substitution, coupling, or acylation reactions, yielding pyridine-containing agrochemical active ingredients |
| Pharmaceuticals | Intermediate for synthesizing antiviral and antitumor agents | Employed as a key structural building block in coupling reactions with aromatic amines and heterocyclic compounds to construct drug molecules featuring a pyridine scaffold |
| Dyes & Pigments | Intermediate for synthesizing high-performance nitrogen-containing heterocyclic dyes | Applied in diazotization and coupling reactions to incorporate chromophores, enabling production of highly stable pyridine-based dyes |
Manufacturing Quality Control of 2,4-DICHLORO-3-AMINOPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities based on retention time and relative response factors versus the main peak. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents using capillary column gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Multi-element quantification of metallic impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion, based on atomic emission intensity. |
| Chloride Content | Potentiometric Titration | Direct titration with silver nitrate using a silver indicator electrode; endpoint determined from potential inflection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary tube method. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C and subsequent weighing. |
| Particle Size Distribution | Laser Diffraction | Size analysis of dry powder via scattering pattern measurement of dispersed particles in an air stream. |
| Bulk Density | Tap Density Tester | Determination of mass per unit volume after controlled mechanical tapping of a known powder mass in a calibrated cylinder. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic bacteria, yeasts, and molds after filtration, membrane transfer to selective agar media, and incubation. |
