Industrial Applications of 1,9-Nonanedithiol
| Industry | Application | Process |
|---|---|---|
| Chemical Synthesis | Organic synthesis intermediate | Used to synthesize sulfur-containing heterocyclic compounds, ligands, and functionalized molecules |
| Polymer Materials | Thiol-ene click reaction crosslinker | Forms crosslinked networks with polyene compounds via photo- or thermal initiation |
| Metal Surface Treatment | Metalsulfide film former | Reacts with metal surfaces to form self-assembled monolayers (SAMs) for improved wettability or corrosion resistance |
| Electronic Materials | Pre-cursor for semiconductor passivation layers | Forms thiol-based protective layers on semiconductor surfaces via chemical vapor deposition (CVD) or spin coating |
| Pharmaceutical Chemistry | Reagent for introducing thiol groups into drug molecules | Serves as a thiol functional group donor in structural modification and coupling reactions of drug molecules |
Manufacturing Quality Control of 1,9-Nonanedithiol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 1,9-nonanedithiol peak area relative to a certified reference standard using external calibration. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standards; measured as APHA units at 455 nm if spectrophotometric. |
| Specific Gravity | Digital Density Meter | Determines density relative to water at 20/20 degC using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light at 20 degC using sodium D-line (589 nm) to assess purity and concentration. |
| Sulfur Content | Combustion IC Analysis (Elemental Analyzer) | Oxidizes sample to SO2, then detects sulfur by infrared absorption or conductivity after catalytic combustion. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at element-specific wavelengths. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Odor Impurities (VOCs) | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identifies and semi-quantifies volatile odor-causing impurities via thermal desorption and mass spectral detection. |
| Appearance | Visual Inspection | Assesses clarity and presence of suspended particles or phase separation against a white background under controlled lighting. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determines lowest temperature at which vapors ignite in presence of flame under standardized closed-cup conditions. |
