Industrial Applications of BIS(TRIMETHYLSILYL) SULFIDE
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Silyl protecting reagent for trimethylsilyl (TMS) protection of functional groups such as alcohols, phenols, and carboxylic acids | Reacted with substrates under anhydrous conditions at room temperature or low temperature, typically using DMF or THF as solvent and a catalytic amount of imidazole or DBU to facilitate the reaction |
| Pharmaceutical Intermediate Synthesis | Critical silylation reagent for selective hydroxyl protection and deprotection cycles in active pharmaceutical ingredient (API) synthesis | Enables high-selectivity silylation of sensitive functional groups (e.g., primary alcohols) in multistep syntheses; subsequent removal under mild acidic conditions (e.g., dilute HCl in methanol) |
| Materials Science | Preparation of silicon-containing precursors for sol-gel synthesis of organic-inorganic hybrid materials | Coprocessed with metal alkoxides via co-hydrolysis and condensation to incorporate flexible Si–O–Si structural units, enhancing material flexibility and hydrophobicity |
| Analytical Chemistry | Derivatization reagent to improve volatility and thermal stability of alcohols and phenols in gas chromatography (GC) or GC-MS analysis | Derivatization carried out at 60–80 °C in the presence of a basic catalyst (e.g., pyridine), yielding volatile TMS derivatives |
Manufacturing Quality Control of BIS(TRIMETHYLSILYL) SULFIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component by retention time and peak area against calibrated standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in methanol/pyridine medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weight after high-temperature ashing. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Detects trace metal elements by atomic emission intensity at characteristic wavelengths. |
| Acid Value | Acid-Base Titration with NaOH | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Refractive Index | Refractometry | Determines purity and consistency by measuring light bending angle in liquid sample at specified temperature. |
| Specific Gravity | Pycnometry | Compares density of sample to water using calibrated glass pycnometer at 20 degrees C. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Quantifies weight loss under controlled heating to assess volatile impurities or decomposition. |
| Sulfur Content | Combustion IC (Ion Chromatography after Combustion) | Oxidizes organic sulfur to sulfate, then detects sulfate ion concentration by IC. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| pH of Aqueous Solution | pH Meter Measurement | Measures hydrogen ion activity in a defined aqueous dilution using calibrated pH electrode. |
