Industrial Applications of 1,8-Dichloro-9,10-bis(phenylethynyl) anthracene
| Industry | Application | Process |
|---|---|---|
| Fluorescent Materials | Intermediate for fluorescent brighteners or fluorescent dyes | Synthesized into strongly fluorescent derivatives via nucleophilic substitution or coupling reactions, applied in whitening treatments for plastics, textiles, or paper |
| Organic Optoelectronic Materials | Building block for organic light-emitting diodes (OLEDs) or organic semiconductors | Conjugated structures are introduced via cross-coupling reactions (e.g., Suzuki or Sonogashira coupling) to tune emission wavelength and charge-carrier mobility |
| Analytical Chemistry | Fluorophore component in fluorescent probes or sensors | Leverages its rigid planar structure and strong fluorescence, combined with recognition groups, for highly sensitive detection of specific ions or molecules |
Manufacturing Quality Control of 1,8-Dichloro-9,10-bis(phenylethynyl) anthracene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on UV absorption of analyte peak area relative to calibration curve using reversed-phase C18 column and appropriate mobile phase. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents by gas chromatography with flame ionization detection using headspace or direct injection. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection of trace metals after acid digestion, based on element-specific atomic emission intensities in high-temperature plasma. |
| Chloride Impurities | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection via visual observation of solid-to-liquid phase change under controlled heating rate. |
| Organic Volatile Impurities (e.g., chlorobenzene, dichlorobenzene) | GC-MS | Identification and quantification of structurally related volatile impurities using mass spectral library matching and selected ion monitoring. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of inorganic ash content by measuring weight loss after high-temperature incineration at 700–800 °C. |
| Particle Size Distribution | Laser Diffraction | Size analysis based on angular variation in intensity of laser light scattered by dispersed particles in liquid or air medium. |
| Specific Optical Rotation | [α]D Measurement (Polarimetry) | Quantification of chiral impurity influence via measurement of plane-polarized light rotation angle at sodium D-line wavelength. |
| Related Substances | HPLC-DAD | Detection and semi-quantification of structurally similar degradation products or synthesis intermediates using diode array detection for spectral confirmation. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Measurement of mass per unit volume after mechanical tapping to assess powder flow and packing characteristics. |
| pH of Aqueous Suspension | pH Meter (with standardized electrode) | Determination of surface acidity/basicity by measuring hydrogen ion activity in a defined aqueous suspension (e.g., 1% w/v). |
