Industrial Applications of 1-PHENYL-1-BUTYNE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Structural building block for synthesizing active molecules such as antitumor agents and protein kinase inhibitors | Used as an alkynylation reagent in Sonogashira coupling, cycloaddition, and other reactions to construct heterocycles or extend carbon chains |
| Organic Synthesis | Preparation of functional material monomers and ligand precursors | Converted into derivatives such as enones, aldehydes, and alcohols via metal-catalyzed (e.g., Pd/Cu) coupling, hydrogenation, hydration, and other reactions |
| Materials Science | Synthetic intermediate for liquid crystal molecules and optoelectronic functional materials | Applied to introduce rigid phenylethynyl structural units, enabling control over molecular anisotropy and conjugation length |
Manufacturing Quality Control of 1-PHENYL-1-BUTYNE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantitative determination based on peak area comparison with a certified reference standard using a suitable capillary column and flame ionization detector. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent; endpoint detected potentiometrically. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Acidity (as HCl) | Acid-Base Titration | Titration with standardized sodium hydroxide solution using phenolphthalein indicator to neutralize acidic impurities. |
| Color | Visual Comparison or Spectrophotometry (APHA Scale) | Comparison of sample color against platinum-cobalt standard solutions or measurement of absorbance at 455 nm in a 10 cm cell. |
| Density | Digital Density Meter | Measurement of oscillation frequency of a U-tube filled with sample, correlated to density via calibration with standards. |
| Refractive Index | Refractometry | Determination of refractive index at 20 degrees C using a calibrated Abbe refractometer and sodium D-line light source. |
| Non-Volatile Matter | Gravimetric Analysis | Evaporation of a specified sample volume at 105 degrees C to constant weight, followed by mass determination of residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using air-acetylene flame AAS with appropriate hollow cathode lamp. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of chlorinated by-products based on retention time and characteristic mass fragments. |
| Peroxide Value | Iodometric Titration | Reaction of peroxides with potassium iodide under acidic conditions to liberate iodine, titrated with standardized sodium thiosulfate. |
| Boiling Range | Distillation (Micro Method) | Determination of initial and final boiling points using a micro distillation apparatus under atmospheric pressure. |
