Industrial Applications of 3,4-DICHLOROPHENYLACETYLENE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for synthesizing antitumor and antiviral drugs | Used in palladium-catalyzed reactions—including Suzuki and Sonogashira couplings—to couple with heterocyclic or aryl boronic acid derivatives, thereby constructing complex pharmacophore scaffolds |
| Agrochemicals | Structural building block for synthesizing novel, high-efficacy insecticides and fungicides | Applied as a chloro-substituted aryl acetylene moiety in nucleophilic substitution or metal-catalyzed coupling reactions to construct biologically active molecular cores |
| Materials Science | Precursor for organic semiconductors and OLED emitters | Processed via vapor deposition or solution-based methods to couple with conjugated systems such as thiophene or carbazole, forming π-conjugated molecules for charge transport layers |
| Chemical Synthesis | High-selectivity organic synthesis intermediate | Applied as an aryl acetylene derivative to construct chloro-substituted polycyclic aromatic hydrocarbons or rigid frameworks, suitable for ligand design and functional molecular assembly |
Manufacturing Quality Control of 3,4-DICHLOROPHENYLACETYLENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on mass spectral fragmentation patterns and retention behavior. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by equilibrium partitioning into headspace followed by GC separation. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities (e.g., Pb, Cd, Hg, As) by atomic emission intensity after plasma atomization. |
| Chloride Ion Impurity | Ion Chromatography (IC) | Separates and quantifies chloride anions using suppressed conductivity detection after ion exchange. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., residual HCl) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting and white background. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Bulk Density | ASTM D1895 Method A | Determines mass per unit volume of freely settled powder using calibrated cylinder and balance. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution by analyzing angular variation in laser light scattering from dispersed particles. |
