| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of pharmaceutical intermediates | Used as an intermediate in the synthesis of anticancer and cardiovascular therapeutic agents |
| Materials Science | Preparation of novel materials | Serves as a raw material for preparing high-performance polymers with specific properties, such as conductive polymers or organic optoelectronic materials |
| Organic Synthesis | Synthesis of complex organic compounds | Applied as a carbon-chain extender or to introduce triple bonds at specific positions during the synthesis of complex organic compounds |
| Analytical Chemistry | Reference standard or calibration substance | Used as a reference standard or calibration substance in gas chromatography for detection and quantification of other compounds |
| Research | Scientific research | Employed in mechanistic studies of organic reactions and in the development of novel organic synthesis methodologies |
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of suspended particles or precipitates under natural light or standard illumination. |
| Purity | Gas Chromatography (GC) | Separate components in the sample using a gas chromatograph; identify compounds by retention time and quantify 5-decyne content via peak area normalization or external standard method. |
| Structure Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) | Determine the infrared absorption spectrum; confirm alkyne structure based on characteristic absorption peaks (e.g., C≡C stretching vibration at approximately 2200 cm⁻¹). |
| Structure Confirmation | Proton Nuclear Magnetic Resonance (¹H-NMR) | Analyze chemical shifts, coupling constants, and integration areas of hydrogen atoms to verify consistency with the molecular hydrogen distribution in 5-decyne. |
| Structure Confirmation | Carbon-13 Nuclear Magnetic Resonance (¹³C-NMR) | Provide information on the carbon skeleton, confirm the position of the alkyne bond and types of carbon atoms, supporting structural identification. |
| Relative Molecular Mass | Mass Spectrometry (MS) | Use electron ionization (EI-MS) or other ionization techniques to detect the molecular ion peak ([M]⁺), determining the relative molecular mass (theoretical value for C₁₀H₁₈: 138.25). |
| Moisture Content | Karl Fischer Titration | Quantitatively determine trace water content through electrochemical titration based on the reaction between iodine and sulfur dioxide in methanol. |
| Density | Density Meter Method / Specific Gravity Bottle Method | Measure liquid density at a specified temperature (e.g., 20°C) using a specific gravity bottle or digital densitometer for physical property verification. |
| Refractive Index | Refractometry | Determine refractive index using an Abbe refractometer at standard temperature as an auxiliary indicator of purity and consistency. |
| Boiling Point | Distillation Method / Differential Scanning Calorimetry (DSC) | Determine boiling range via atmospheric distillation, or use DSC to analyze phase transition temperatures, confirming whether the boiling point matches that of 5-decyne (approximately 170–175°C). |
| Impurity Analysis | GC-MS Coupled Technique | Combine gas chromatography with mass spectrometry to separate and structurally identify impurities, suitable for detection and quantification of trace organic impurities. |
| Acid Value / Neutrality Test | Acid-Base Titration | Titrate free acid content in the sample with a standardized alkaline solution to assess potential oxidative or hydrolytic degradation products formed during storage. |
