Industrial Applications of 3-Pyridinecarboxylic acid, 2,4-dichloro-, Methyl ester
| Industry | Application | Process |
|---|---|---|
| Pesticides | Used as a herbicide intermediate for synthesizing sulfonylurea- or pyrimidinyloxybenzoic acid–based herbicides (e.g., florasulam) | Serves as a key intermediate in multistep organic synthesis, typically involving esterification, chlorination, and subsequent coupling reactions to construct the active molecular scaffold |
| Pharmaceuticals | Used as a drug synthesis intermediate for developing biologically active nitrogen-containing heterocyclic compounds | Employed in pharmaceutical chemical synthesis to construct pyridine or nicotinic acid derivative core structures, with target functional groups introduced via hydrolysis, amination, or metal-catalyzed coupling reactions |
| Fine Chemicals | Used to synthesize high-value fine chemicals, such as liquid crystal materials or functional molecules | Prepares specific structural units through selective functional group transformations (e.g., reduction, substitution) for downstream synthesis of advanced materials |
Manufacturing Quality Control of 3-Pyridinecarboxylic acid, 2,4-dichloro-, Methyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220-254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification and reporting of individual impurities above threshold limits. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, dichloromethane) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion and isotopic dilution calibration. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode to detect endpoint based on AgCl precipitation potential shift. |
| Acid Value | Acid-Base Titration | Titration with standardized NaOH solution using phenolphthalein indicator to determine free acid impurities from hydrolysis. |
| Appearance | Visual Inspection | Comparison of sample solution in clear solvent (e.g., acetonitrile) against water-white standard under controlled lighting and viewing conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature range using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (600-800 C) to assess inorganic ash content. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light at 20 C using sodium D-line to confirm chiral purity and identity. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using laser scattering to determine D10, D50, D90 values per ISO 13320. |
