Industrial Applications of 1-UNDECYNE
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Intermediate for synthesizing functionalized alkynes, conjugated enynes, and heterocyclic compounds | Sonogashira coupling, Glaser coupling, and cycloaddition reactions (e.g., [2+2], [3+2]) |
| Materials Science | Building block for conductive polymers with controllable carbon chain length and ligands for metal–organic frameworks (MOFs) | Cross-coupling of terminal alkynes with aryl/alkyl halides or CuAAC “click” chemistry with azides |
| Pharmaceutical R&D | Introduction of a hydrophobic undecynyl side chain into drug molecules to modulate pharmacokinetic properties | Selective alkyne derivatization of active molecules, typically via palladium-catalyzed C–H activation or substitution reactions |
Manufacturing Quality Control of 1-UNDECYNE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1-undecyne peak area relative to calibration standards using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Evaporation | Gravimetric Analysis | Evaporates a known sample mass at controlled temperature and weighs non-volatile residue. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to APHA platinum-cobalt standard solutions using visual or spectrophotometric measurement at 430 nm. |
| Density at 20 C | Digital Density Meter | Determines density by oscillating U-tube principle measuring resonant frequency shift in filled sample cell. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through liquid sample using Abbe refractometer or digital equivalent. |
| Boiling Point Range | Distillation (ASTM D86 or D1078) | Determines initial and final boiling points under atmospheric pressure using standardized distillation apparatus. |
| Unsaturates (Alkynes other than 1-undecyne) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies structural isomers and homologous alkynes based on retention time and mass fragmentation patterns. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chlorinated Impurities | Gas Chromatography with Electron Capture Detector (GC-ECD) | Detects trace chlorinated compounds via high electron affinity leading to enhanced signal response. |
| Peroxide Value | Iodometric Titration | Measures peroxides by oxidation of iodide to iodine, followed by titration with standardized sodium thiosulfate. |
