Industrial Applications of NISTC17887808
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Silyl protecting reagent for selective protection of functional groups such as alcohols, phenols, and carboxylic acids | Reacted with substrates under anhydrous, inert atmosphere and basic conditions (e.g., NaH, n-BuLi) to form silyl ether protected products |
| Pharmaceutical Intermediates | Precursor or structural modification reagent in the synthesis of silicon-containing drug molecules | Participates in coupling reactions or serves as a silylation reagent to introduce trimethylsiloxy side chains during API synthesis |
| Materials Science | Crosslinking modifier or modifying monomer for organosilicon resins and silicone rubbers | Acts as a bridging unit in condensation reactions to enhance polymer flexibility and thermal stability |
| Analytical Chemistry | Derivatization reagent to improve volatility and detection sensitivity in gas chromatography–mass spectrometry (GC-MS) analysis | Undergoes silylation derivatization with compounds containing active hydrogen (e.g., hydroxyl, amino groups) under catalysis (e.g., BSTFA) |
Manufacturing Quality Control of NISTC17887808
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co scale) | Evaluates yellowness by comparing sample color to platinum-cobalt standard solutions at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Measures mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample at specified temperature using critical angle measurement. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of known sample mass under nitrogen at defined temperature. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state atoms in flame or graphite furnace after acid digestion and matrix modification. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling impurities by analyzing vapor phase above heated sample using GC-FID or GC-MS. |
| Silicon Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies total silicon after acid digestion by measuring element-specific atomic emission intensity. |
| Residual Solvents | Gas Chromatography (GC) with Headspace or Direct Injection | Identifies and quantifies common solvents (e.g., hexane, toluene) using calibrated GC-FID or GC-MS. |
