Industrial Applications of 1-ETHYNYLCYCLOHEXENE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate for synthesizing steroids and hormonal drugs | Alkynyl group introduced via Sonogashira coupling, followed by cyclization or functional group transformation |
| Organic Synthesis | Structural building block for constructing polycyclic and bridged-ring compounds | Acts as an electrophilic alkyne in Diels–Alder reactions and transition metal-catalyzed cycloadditions such as [2+2+2] cyclotrimerization |
| Materials Science | Monomer for high-performance polymers (e.g., polyalkynes, functionalized polyacetylene derivatives) | Radical or metal-catalyzed polymerization; or Cadiot–Chodkiewicz coupling with dihaloarenes to prepare conjugated polymers |
Manufacturing Quality Control of 1-ETHYNYLCYCLOHEXENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected by current change. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile residue after controlled high-temperature ashing and subsequent weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals via absorption of characteristic atomic spectral lines after acid digestion. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using an anion-exchange column and conductivity detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluation of sample color intensity against APHA platinum-cobalt standards using 455 nm absorbance or matched glass standards. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer or digital equivalent. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporation of a known sample mass under controlled conditions followed by weighing of residual solids. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by organic peroxides to liberate iodine, titrated with standardized sodium thiosulfate. |
| Residual Solvents (e.g., Hexane, Ethanol) | Headspace Gas Chromatography (HS-GC) | Thermal equilibration of sample in sealed vial, followed by GC-FID analysis of volatile components in headspace gas. |
