Industrial Applications of 3-CHLORO-5-METHYLPYRIDINE
| Industry | Application | Process |
|---|---|---|
| Pesticides | Key intermediate in the synthesis of chlorpyrifos insecticide | Used to produce pyridine-based organophosphorus insecticides via reaction of 3-chloro-5-methylpyridine with O,O-diethyl thiophosphoryl chloride and other reagents |
| Pharmaceuticals | Intermediate for synthesizing bioactive pyridine-containing pharmaceuticals | Serves as a precursor for nitrogen-containing heterocyclic structures; employed in coupling and substitution reactions to prepare anti-inflammatory, antitumor, and other therapeutic molecules |
| Fine Chemicals | Synthesis of other functionalized pyridine derivatives | Subjected to chemical modifications—including halogen exchange, oxidation, and amination—to produce high-value specialty chemicals |
Manufacturing Quality Control of 3-CHLORO-5-METHYLPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| Related Substances | Gas Chromatography (GC) with FID or MS detection | Separation and identification of impurities by retention time and/or mass spectral matching; quantified relative to main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents are vaporized in sealed vials, then injected and separated on a capillary column for quantification. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Chloride Ion Impurity | Ion Chromatography (IC) with conductivity detection | Anions separated on an ion-exchange column and detected via changes in electrical conductivity after suppression. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Sample digested and atomized/ionized in plasma; elemental masses detected with high sensitivity and multi-element capability. |
| Acidity (as HCl) | Acid-Base Titration with NaOH standard solution | Free acid content determined by neutralization with standardized sodium hydroxide using potentiometric or indicator endpoint detection. |
| Color | Visual Comparison against APHA Color Standard | Sample color assessed in a 100-mm cell under controlled lighting by matching to platinum-cobalt scale standards. |
| Density at 20 degC | Oscillating U-tube Densitometry | Density calculated from the resonant frequency of a vibrating U-shaped glass tube filled with sample at controlled temperature. |
| Refractive Index at 20 degC | Refractometry (Abbe type) | Measurement of light refraction angle at air-sample interface using calibrated prism; converted to refractive index value. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Sample evaporated to dryness at specified temperature; residue weighed to determine inorganic/organic non-volatile content. |
| Melting Point | Capillary Melting Point Apparatus | Solid sample heated gradually in capillary tube; onset and clear point recorded as temperature range where phase transition occurs. |
