Industrial Applications of 4,6-DICHLORO-3-PYRIDINEMETHANOL
| Industry | Application | Process |
|---|---|---|
| Agrochemicals | Key intermediate for neonicotinoid insecticides, such as imidacloprid and thiacloprid | Serves as a building block for the bipyridyl ring system; undergoes nucleophilic substitution with nitroimidazole compounds to synthesize target agrochemicals |
| Pharmaceuticals | Synthetic intermediate for specific pyridine-based pharmaceutical compounds | Undergoes chemical modifications—including coupling, etherification, or oxidation—via functional groups (chlorine atom and hydroxymethyl group) on the pyridine ring to construct drug molecule scaffolds |
| Fine Chemicals | Functional intermediate for pyridine derivatives | Processed via dechlorination/hydrogenolysis, hydroxyl oxidation, or esterification to produce other high-value fine chemicals or ligands |
Manufacturing Quality Control of 4,6-DICHLORO-3-PYRIDINEMETHANOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., methanol, dichloromethane) using gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine-based reagent; water reacts stoichiometrically to determine trace moisture content. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using light scattering principles to determine D10, D50, D90 values. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution, reported as [alpha]D value. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Microbial Limits | Membrane Filtration + Culture | Enumeration of aerobic mesophilic bacteria and fungi via filtration, membrane transfer to selective agar media, and incubation per USP <61> and <62>. |
