Industrial Applications of Benzeneacetic acid, 2,5-dichloro-
| Industry | Application | Process |
|---|---|---|
| Pesticides | Key intermediate for synthesizing the herbicide 2,4-dichlorophenoxybutyric acid (2,4-DB) | Esterified with 1-butanol under acidic conditions, followed by chlorination and hydrolysis to produce 2,4-DB |
| Pharmaceuticals | Precursor for synthesizing the nonsteroidal anti-inflammatory drug flurbiprofen | Multi-step synthesis involving acid chloride formation, Friedel–Crafts acylation, decarboxylation, and fluorination to construct the biphenylpropionic acid structure |
| Chemicals | Organic synthesis intermediate for dyes, photosensitive materials, and functional polymer monomers | Aryl groups introduced via palladium-catalyzed coupling (e.g., Suzuki reaction), or chlorinated phenethylamine derivatives prepared via reductive amination |
Manufacturing Quality Control of Benzeneacetic acid, 2,5-dichloro-
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Related Substances | HPLC with UV detection | Separation and quantification of structurally related impurities using gradient elution and UV absorbance detection. |
| Residual Solvents | Gas Chromatography (GC) with FID | Identification and quantification of volatile organic solvents by retention time matching and peak area integration. |
| Heavy Metals | ICP-OES | Multi-element quantification of metallic impurities after acid digestion, based on atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Potentiometric titration with AgNO3 | Determination of chloride ions via argentometric titration using a silver indicator electrode and endpoint detection. |
| Moisture Content | Karl Fischer titration | Quantitative measurement of water content based on stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol. |
| Melting Point | Capillary melting point apparatus | Thermal transition detection by observing the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Solubility in Common Solvents | Gravimetric dissolution test | Qualitative or semi-quantitative evaluation of complete dissolution in specified solvents (e.g., methanol, acetone) at defined temperature and concentration. |
| pH of Aqueous Suspension | pH meter measurement | Determination of hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Residue on Ignition | Gravimetric analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (500-600 C) and subsequent weighing. |
| Particle Size Distribution | Laser diffraction | Analysis of size distribution based on angular dependence of scattered laser light intensity from a dispersed sample. |
