Industrial Applications of 4-PHENYL-1-BUTYNE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Structural building block for synthesizing active molecules such as antitumor agents and protein kinase inhibitors | Constructs heterocyclic or functionalized molecular scaffolds via reactions including Sonogashira coupling, hydrogenation, and cyclization |
| Organic Synthesis | Alkyne-based building block for click chemistry, cycloaddition, and metal-catalyzed coupling reactions | Introduces a C4 alkyne chain into substrates, followed by Pd/Cu-catalyzed cross-coupling with aryl or alkenyl halides |
| Materials Science | Monomer for preparing conjugated polymers and organic optoelectronic materials | Forms diyne structures via Glaser or Eglinton coupling, or copolymerizes with boronic acid- or stannane-containing reagents to build π-conjugated systems |
Manufacturing Quality Control of 4-PHENYL-1-BUTYNE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 4-phenyl-1-butyne peak area relative to a calibrated standard curve. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separates and quantifies volatile solvents based on retention time and detector response. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Compares sample color to platinum-cobalt standards or measures absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume from resonant frequency of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry | Measures bending of light through the sample at specified temperature to assess purity and composition. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion by atomic emission spectroscopy. |
| Chloride Content | Ion Chromatography (IC) | Separates and detects chloride ions based on ion exchange and conductivity detection. |
| Non-Volatile Residue | Gravimetric Analysis | Measures residue weight after evaporation of a defined sample volume under controlled heating. |
| Alkali Metals (Na, K) | Flame Photometry | Quantifies alkali elements by measuring characteristic emission intensity in a flame. |
| Peroxide Value | Iodometric Titration | Measures peroxides via oxidation of iodide to iodine, followed by thiosulfate titration. |
