Industrial Applications of 87184-99-4
| Industry | Application | Process |
|---|---|---|
| Chemical Synthesis | Used as a protecting group in organic synthesis, particularly in the preparation of complex natural products and pharmaceutical molecules | Reacted with alcohols to form the corresponding tert-butyldimethylsilyl ethers, thereby protecting hydroxyl groups from participating in subsequent reactions; the protecting group is subsequently removed using fluoride-based deprotection reagents when required |
| Pharmaceuticals | Employed in the synthesis of antibiotics, antiviral agents, and other pharmaceutical intermediates | Added at specific steps—e.g., 4-(tert-butyldimethylsilyloxy)-1-butanol—to protect critical functional groups, ensuring selective synthesis of the target compound |
| Fine Chemicals | Applied as a temporary protecting agent in the manufacturing processes of certain specialty chemicals or materials | Subjected to standard silylation conditions for protection, followed by deprotection under appropriately selected conditions as needed |
Manufacturing Quality Control of 87184-99-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component relative to internal/external standard using retention time and peak area. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and characteristic mass spectra. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects volatile organic solvents by equilibrium partitioning into headspace followed by GC separation. |
| Water Content | Karl Fischer Titration (Coulometric) | Measures water via electrochemical iodine generation and stoichiometric reaction with water. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after controlled high-temperature ashing. |
| Heavy Metals | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Quantifies metal impurities (e.g., Pb, Cd, Ni, Fe) by atomic emission intensity at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Refractive Index | Refractometry | Measures ratio of light velocity in air vs. sample at specified temperature and wavelength (e.g., 20 deg C, sodium D line). |
| Specific Gravity | Digital Density Meter | Determines density relative to water via oscillating U-tube principle. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting. |
| Free Tert-Butanol | Gas Chromatography (GC) with FID | Quantifies residual tert-butanol using calibrated external standard and selective retention time. |
